x\times 100=120x-480-80
Use the distributive property to multiply 120 by x-4.
x\times 100=120x-560
Subtract 80 from -480 to get -560.
x\times 100-120x=-560
Subtract 120x from both sides.
-20x=-560
Combine x\times 100 and -120x to get -20x.
x=\frac{-560}{-20}
Divide both sides by -20.
x=28
Divide -560 by -20 to get 28.
