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
solve:
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!

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!
