Maybe the reason that you are getting stuck is because you don't have to factor at all.

$\displaystyle (3x-4)-(5x-8)=-(x+12)-6+1$

$\displaystyle 3x-4-5x+8=-x-12-6+1$

$\displaystyle -2x+4=-x-17$

$\displaystyle x=-21$

By the way, you should post these types of problems in the pre-algebra algebra sub-forum
