Answer:


x = 7

Explanation:

To solve for
x you need to isolate the
x terms to one side. We have to get rid of the negative 8. To get 0 from -8 we need to add 8. Anything you do to one side you do the other so:


3x- 8 = 13 : Add 8 to both sides.


3x = 21 : Now we have 3
x but we only want one. So divide both sides by 3.


x = 7
