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.

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.

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.

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 ]

These comparisons are provided for informational purposes only. Actual results may vary depending on several factors.

Why responses may vary

AI models are non-deterministic — the same question can produce different answers across runs. The responses shown here are representative snapshots captured at a specific point in time and may differ from what you receive today. Providers also update their models regularly, which can change response quality, tone and length.

Key factors affecting credit consumption

Credit usage depends on the length of the question and answer (token count), the specific model used and the complexity of the task. Longer or more complex responses consume more credits. Generation time depends on model size, provider load and response length, and does not directly affect the credit cost.
