add to both sides
subtract from both sides
multiply both sides
divide both sides

Explanation:

Step1: Subtract $\frac{2}{5}$ from both sides

$\frac{2}{5} - \frac{x}{5} - \frac{2}{5} = \frac{4}{5} - \frac{2}{5}$
$-\frac{x}{5} = \frac{4-2}{5}$
$-\frac{x}{5} = \frac{2}{5}$

Step2: Multiply both sides by 5

$-\frac{x}{5} \times 5 = \frac{2}{5} \times 5$
$-x = 2$

Step3: Multiply both sides by -1

$-x \times (-1) = 2 \times (-1)$
$x = -2$

Answer:

$x=-2$
