$x=-57$

#### Work Step by Step

The distributive property allows us to distribute anything multiplied by something inside of the parenthesis to whatever is inside of the parenthesis. Thus, we distribute the 3 to everything inside of the first set of parenthesis, the 2 to everything inside of the second set of parenthesis, the -4 to everything in the third set of parenthesis, and the 10 to everything in the fourth set of parenthesis, giving us the equation:
$3x-3+2x-6=-4x+8+10x+40$
We now simplify:
$5x-9=6x+48 \\\\ -9=x+48 \\\\ x=-57$
