#### Answer

x = $\frac{5}{20}$ = $\frac{1}{4}$

#### Work Step by Step

x -$\frac{2}{5}$ = -$\frac{3}{20}$ x - $\frac{2}{5}$ + $\frac{2}{5}$ = -$\frac{3}{20}$ + $\frac{2}{5}$ x = -$\frac{3}{20}$ + $\frac{2}{5}$ $\times$ $\frac{4}{4}$ x = -$\frac{3}{20}$ + $\frac{8}{20}$ x = $\frac{5}{20}$ = $\frac{1}{4}$
