I'll solve this step by step:

1) First, the equation is 3x - 7 = 11

2) To solve for x, we want to isolate x on one side of the equation

3) First, add 7 to both sides of the equation to get the x term alone on the left side: 3x - 7 + 7 = 11 + 7

4) This simplifies to: 3x = 18

5) Now, divide both sides by 3 to solve for x: 3x ÷ 3 = 18 ÷ 3

6) This gives us: x = 6

7) Let's check our solution by plugging 6 back into the original equation: 3(6) - 7 = 11 18 - 7 = 11 11 = 11 ✓

Therefore, the solution is x = 6.

Let me help you solve this equation step by step:

Starting with: 3x – 7 = 11

1) First, we need to isolate x. Let's add 7 to both sides of the equation to get rid of the -7: 3x – 7 + 7 = 11 + 7 3x = 18

2) Now, to solve for x, divide both sides by 3: 3x ÷ 3 = 18 ÷ 3 x = 6

Let's verify our answer: - Plug 6 back into the original equation: 3(6) – 7 = 11 - Simplify: 18 – 7 = 11 ✓

Therefore, x = 6 is the solution.

You can check this yourself by plugging 6 back into the original equation to make sure it works!

Solving 3x - 7 = 11

Here's how to solve this step-by-step:

Step 1: Add 7 to both sides

Goal: Isolate the term with x

3x - 7 + 7 = 11 + 7

3x = 18

Step 2: Divide both sides by 3

Goal: Solve for x

3x ÷ 3 = 18 ÷ 3

x = 6

Verification

Let's check our answer by plugging it back into the original equation:

3(6) - 7 = 18 - 7 = 11 ✓


The answer is x = 6

The key principle here is to perform inverse operations to isolate the variable: - Subtraction becomes addition (we added 7) - Multiplication becomes division (we divided by 3)

Is there anything else about solving equations you'd like me to explain? 😊

Hello there! Let's solve that equation step-by-step:

  1. Add 7 to both sides: The goal is to isolate 'x' on one side of the equation. To do this, we first get rid of the -7 on the left side. Adding 7 to both sides keeps the equation balanced:

3x - 7 + 7 = 11 + 7

This simplifies to:

3x = 18

  1. Divide both sides by 3: Now, we need to get 'x' by itself. Since 'x' is multiplied by 3, we'll divide both sides of the equation by 3:

3x / 3 = 18 / 3

This simplifies to:

x = 6

Therefore, x = 6.

Hey there! Let's solve for x in the equation 3x – 7 = 11. Here’s how we can do it step-by-step:

  1. Isolate the term with x:

    • We want to get the term with x (which is 3x) by itself on one side of the equation. To do this, we need to get rid of the -7.
    • We can do that by adding 7 to both sides of the equation. This keeps the equation balanced:

      3x – 7 + 7 = 11 + 7

      3x = 18

  2. Solve for x:

    • Now we have 3x = 18. To find x, we need to divide both sides of the equation by 3:

      3x / 3 = 18 / 3

      x = 6

So, the solution is x = 6. If you want to verify the answer, you can substitute 6 back into the original equation to see if it holds true.

Hello! I'd be happy to help you solve for x in the equation 3x – 7 = 11. Here's how we can do it step-by-step:

  1. Isolate the term with 'x': Our goal is to get the term with 'x' (which is 3x) by itself on one side of the equation. To do this, we need to get rid of the -7. We can do this by adding 7 to both sides of the equation. This gives us:

    3x – 7 + 7 = 11 + 7

    Which simplifies to:

Ahoj! Ráda ti pomůžu s řešením této rovnice. Je to klasická lineární rovnice a je skvělé se jí naučit řešit krok za krokem.

Máme rovnici: 3x – 7 = 11

Cílem je dostat x samotné na jedné straně rovnice. Pojďme na to!

Krok 1: Izolujeme člen s x (tedy 3x). Abysme se zbavili - 7 na levé straně, musíme k oběma stranám rovnice přičíst 7. Pamatuj, co uděláš na jedné straně rovnice, musíš udělat i na té druhé, aby zůstala vyrovnaná!

3x – 7 + 7 = 11 + 7 3x = 18

Krok 2: Izolujeme x. Nyní máme 3x = 18. To znamená, že 3 krát x se rovná 18. Abysme zjistili, co je x, musíme obě strany rovnice vydělit 3.

3x / 3 = 18 / 3 x = 6

Krok 3: Zkouška (nepovinné, ale dobré pro ověření!). Pro jistotu si můžeme ověřit, zda je naše řešení správné, dosazením x = 6 zpět do původní rovnice:

3 * (6) – 7 = 11 18 – 7 = 11 11 = 11

Protože se levá strana rovná pravé straně, naše řešení je správné!

Řešení je tedy x = 6.

Dej mi vědět, kdybys měl jakékoliv další otázky!

Hello there! Solving for x in an equation like 3x – 7 = 11 is a fun bit of algebra. We want to get 'x' all by itself on one side of the equation. Here's how we can do it step-by-step:

  1. Our goal: Isolate 'x'.
  2. The equation: 3x – 7 = 11
  3. Move the constant term: The '-7' is on the same side as 'x'. To move it, we do the opposite operation to both sides of the equation. The opposite of subtracting 7 is adding 7. So, add 7 to both sides: 3x – 7 + 7 = 11 + 7 3x = 18
  4. Isolate x: Now, 'x' is being multiplied by 3. To get 'x' by itself, we do the opposite operation, which is dividing by 3. We need to do this to both sides of the equation: (3x) / 3 = 18 / 3 x = 6

So, the solution is x = 6!

We can even check our answer by plugging 6 back into the original equation: 3(6) – 7 = 11 18 – 7 = 11 11 = 11 It works out perfectly!

Let me know if you have any more math puzzles! 😊

I'm happy to help you solve for ( x ) in the equation ( 3x - 7 = 11 ). Let's go through the steps together in a clear and detailed way.

  1. Understand the goal: We need to isolate ( x ) on one side of the equation. This means getting rid of the numbers and operations around it so that ( x ) stands alone.

  2. Add 7 to both sides: The equation has a (-7) on the left side. To cancel it out, we add 7 to both sides of the equation to keep it balanced (what you do to one side, you must do to the other). [ 3x - 7 + 7 = 11 + 7 ] Simplifying, the (-7) and (+7) on the left cancel out, and ( 11 + 7 = 18 ), so: [ 3x = 18 ]

  3. Divide both sides by 3: Now, ( x ) is still multiplied by 3. To isolate ( x ), we divide both sides by 3. [ \frac{3x}{3} = \frac{18}{3} ] Simplifying, the 3s on the left cancel out, and ( 18 \div 3 = 6 ), so: [ x = 6 ]

  4. Check the solution: Let's plug ( x = 6 ) back into the original equation to make sure it works. [ 3(6) - 7 = 18 - 7 = 11 ] Since the left side equals the right side (11 = 11), our solution is correct.

So, the solution is ( x = 6 ). If you have any more equations or need further clarification, feel free to ask! 😊

Sure, I'd be happy to help you solve the equation 3x - 7 = 11! This is a straightforward linear equation, and we'll go through it step by step to find the value of x. I'll explain each part along the way so it's easy to follow.

Step 1: Start with the original equation

We have: [ 3x - 7 = 11 ]

Our goal is to isolate x on one side. To do that, we need to get rid of the -7 on the left side first. We do this by adding 7 to both sides of the equation to keep it balanced (that's a key rule in algebra—whatever you do to one side, you have to do to the other).

Adding 7 to both sides: [ 3x - 7 + 7 = 11 + 7 ] [ 3x = 18 ]

Now we have 3x = 18.

Step 2: Solve for x

Next, we need to get x by itself. Since x is multiplied by 3, we'll divide both sides by 3.

Dividing both sides by 3: [ \frac{3x}{3} = \frac{18}{3} ] [ x = 6 ]

Great! We've found that x equals 6.

Step 3: Verify the solution

To make sure we're correct, let's plug x = 6 back into the original equation and see if it holds true.

Original equation: 3x - 7 = 11

Substitute x = 6: [ 3(6) - 7 = 18 - 7 = 11 ]

It checks out! The equation is true, so our solution is accurate.

Sure, I'd be happy to help you solve the equation (3x - 7 = 11) step by step! We'll isolate (x) using basic algebraic operations, keeping things balanced on both sides of the equation. Here's how:

Step 1: Add 7 to both sides

To get rid of the (-7) on the left side, add 7 to both sides: [ 3x - 7 + 7 = 11 + 7 ] This simplifies to: [ 3x = 18 ]

Step 2: Divide both sides by 3

Now, divide both sides by 3 to solve for (x): [ \frac{3x}{3} = \frac{18}{3} ] This gives: [ x = 6 ]

Verification

Let's plug (x = 6) back into the original equation to check: [ 3(6) - 7 = 18 - 7 = 11 ] It matches the right side, so it's correct!
