\frac{5}{2}x=20
Add 20 to both sides. Anything plus zero gives itself.
x=20\times \frac{2}{5}
Multiply both sides by \frac{2}{5}, the reciprocal of \frac{5}{2}.
x=\frac{20\times 2}{5}
Express 20\times \frac{2}{5} as a single fraction.
x=\frac{40}{5}
Multiply 20 and 2 to get 40.
x=8
Divide 40 by 5 to get 8.
