this is how i worked it out:

2(12-8x)=x-11x

24-16x=1x-11x

-1x

24-16x= -12x

-(-12)

24=-4x

-6=x

**Ms. Sue**, Wednesday, January 12, 2011 at 5:43pmHere's your mistake.

24-16x=1x-11x

24 - 16x =**-10x**

24 = -10x + 16x

24 = 6x

24/6 = x

4 = x

24-16x=1x-11x

-1x

24-16x= -12x 24 - 16x = -10x

-(-12) 24 = 6x

24=-4x x = 4

-6=x
