I have a math CRCT test today and I needed some help on a last minute review problem.

Can someone please explain how to solve this?

1. 12x-3+6x-2=31

add the x's and "move" the constants to the other side ---->

12x+6x = 31 + 3 + 2

18x = 36

divide both sides by 18

18x/18 = 36/18

x = 2

Combine like terms.

18x -5 = 31

Add 5 to both sides.

18x = 36

Divide by 18.

x = 2

I hope this helps. Thanks for asking.
