-3%284x-4%29-12=-3%287x%2B6%29-4 Start with the given equation.


-12x%2B12-12=-21x-18-4 Distribute.


-12x=-21x-18-4 Combine like terms on the left side.


-12x=-21x-22 Combine like terms on the right side.


-12x%2B21x=-22 Add 21x to both sides.


9x=-22 Combine like terms on the left side.


x=%28-22%29%2F%289%29 Divide both sides by 9 to isolate x.

Answer:

So the solution is x=-22%2F9

I'll let you do the check.
