unsimplified answer: - 38/30
simplified answer: -1 4/15
Explanation
3x+4(x-8+2-3x+6x-8+2(x+7)=12x-5(x+1)-7x+8(x-2)+9x-20x+6-1
first,distribute the 2(x+7)
3x+4(x-8+2-3x+6x-8+2x+14)=12x-5(x+1)-7x+8(x-2)+9x-20x+6-1
second, distribute all
3x+4x-32+8-12x+24x-32+8x+56=12x-5x+5-7x+8x-16+9x-20x+6-1
next,combine like terms
27x+32=-3x-6
then, isolate x but allow for a coefficient on x
38=-30x
finally,completely isolate x
x= - 38/30
simplify if needed.
