**Reiny**, Wednesday, April 22, 2009 at 11:51amadd 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

**PsyDAG**, Wednesday, April 22, 2009 at 11:52amCombine like terms.

18x -5 = 31

Add 5 to both sides.

18x = 36

Divide by 18.

x = 2

I hope this helps. Thanks for asking.
