12-3%28x%2B2%29=x%2B8 Start with the given equation.


12-3x-6=x%2B8 Distribute.


-3x%2B6=x%2B8 Combine like terms on the left side.


-3x=x%2B8-6 Subtract 6 from both sides.


-3x-x=8-6 Subtract x from both sides.


-4x=8-6 Combine like terms on the left side.


-4x=2 Combine like terms on the right side.


x=%282%29%2F%28-4%29 Divide both sides by -4 to isolate x.


x=-1%2F2 Reduce.

Answer:

So the solution is x=-1%2F2
