4%28x%2B5%29=x%2B8 Start with the given equation.


4x%2B20=x%2B8 Distribute.


4x=x%2B8-20 Subtract 20 from both sides.


4x-x=8-20 Subtract x from both sides.


3x=8-20 Combine like terms on the left side.


3x=-12 Combine like terms on the right side.


x=%28-12%29%2F%283%29 Divide both sides by 3 to isolate x.


x=-4 Reduce.
