\frac{4}{5}x=20
Add 20 to both sides. Anything plus zero gives itself.
x=20\times \frac{5}{4}
Multiply both sides by \frac{5}{4}, the reciprocal of \frac{4}{5}.
x=\frac{20\times 5}{4}
Express 20\times \frac{5}{4} as a single fraction.
x=\frac{100}{4}
Multiply 20 and 5 to get 100.
x=25
Divide 100 by 4 to get 25.
