solve:

Question

4x+18=22

please help. i just need to understand how to do this for i have many problems like this on my final, and i have forgotten how!

Answer 1

You want everything with x in it on the left and everything without x on the right
So
add -18 to both sides
then divide both sides by 4 to get 1x instead of 4x

Answer 2

4x+18=22

First, subtract the known number on the left side from each side of the equation.

4x + 18 - 18 = 22 - 18
4x = 4

Divide both sides of the equation by 4.

x = 1

Let's prove it.
4 * 1 + 18 = 22

Yep. It's right!
