-2(x-3)+5x+7=3(4-3x)+12x-9 - problem
-2x+6+5x+7=3(4x-3x)+12x-9 - distributive property
5x-2x+6+7=3(4x-3x)+12x-9 - combine like terms
3x+13=3(4x-3x)+12x-9 - combine like terms
3x+13=12x-9x+12x-9 - distributive property
3x+13=3x+12x-9 - combine like terms
3x+13=15x-9 - combine like terms
13=12x-9 - subtract 3x from both sides
22=12x - add 9 to both sides
x=0.5454

-2x + 6 + 5x + 7 = 12 - 9x + 12x - 9
3x + 13 = 3x + 3
0 = -10
