Question

3x - 14 + 4 + 2x + (-18 + 3x)=180

Answer 1

x = 26.

Explanation:

3x - 14 + 4 + 2x + (-18 + 3x)=180

3x - 14 + 4 + 2x - 18 + 3x = 180

3x + 3x + 2x = 180 + 14 - 4 + 18

8x = 208

x = 208/8

= 26.

Answer 2

Answer: x=26

Let’s start with rewriting the equation

3x-14+4+2x+(-18+3x)=180

Now let’s distribute. We’ll do this by multiplying the 1 with the -18, and the 1 with the 3x.

3x-14+4+2x+(-18+3x)=180

3x-14+4+2x-18+3x=180

Now let’s combine like terms. These are the numbers that share the same variable, or lack of.

3x-14+4+2x-18+3x=180

8x-28=180

Our goal is to get x alone on the left side. Our first step in doing this is to add 28 on both sides.

8x-28=180
+28 +28
_________
8x=208

Now to finally get x alone on the left side (and get our final answer) we need to divide 8x and 208 by 8.

8x=208

8x/8=208/8

x=26

This is the final answer!
