80=80\times 25x
Subtract 120 from 200 to get 80.
80=2000x
Multiply 80 and 25 to get 2000.
2000x=80
Swap sides so that all variable terms are on the left hand side.
x=\frac{80}{2000}
Divide both sides by 2000.
x=\frac{1}{25}
Reduce the fraction \frac{80}{2000} to lowest terms by extracting and canceling out 80.
