Question

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

Answer 1

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

Answer 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.

Answer 3

Thanks! I realllyyy hope I pass this!!
