4x-16=80 Start with the given equation



4x=80%2B16Add 16 to both sides


4x=96 Combine like terms on the right side


x=%2896%29%2F%284%29 Divide both sides by 4 to isolate x



x=24 Divide

--------------------------------------------------------------
Answer:
So our answer is x=24



Check:

4x-16=80 Start with the given equation


4%2824%29-16=80 Plug in x=24


96-16=80 Multiply


80=80 Subtract. Since the two sides of the equation are equal, this verifies our answer.
