Shawn, So, for -12/3x(-8+(-4)^2-6)+2= -6, then x must equal 1.

Steve, do you think Shawn knows that you substituted 1 for x? I am asking because x sort of disappeared?
*September 18, 2015*

**Math**

ok, let's simplify the equation first. -12/3 x(-8+(-4)^2-6)+2 = -12/3 x(-8+16-6)+2 = -12/3 x(2)+2 = -4x(2)+2 = -8x+2 now, if -8x+2=-6, then subtract 2 from each side of the equation, then -8x=-8, multiply each side by -1/8 then x=1
