10=x\left(200+50\right)
Multiply 50 and 0.2 to get 10.
10=x\times 250
Add 200 and 50 to get 250.
x\times 250=10
Swap sides so that all variable terms are on the left hand side.
x=\frac{10}{250}
Divide both sides by 250.
x=\frac{1}{25}
Reduce the fraction \frac{10}{250} to lowest terms by extracting and canceling out 10.
