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.
