$x = \frac{12}{5}$ $x=12/5$

$\Rightarrow \frac{1}{2} x - \frac{2}{5} = \frac{4}{5}$ $=> 1/2x - 2/5 = 4/5$

Add $\frac{2}{5}$ $2/5$ on both the sides

$=>1/2x - cancel(2/5) + cancel(2/5) = 4/5 + 2/5$

$=> 1/2x = 4/5 + 2/5$

$=> 1/2x = (4 + 2)/5$

$=> 1/2x = 6/5$

Multiply both sides by $2$

$=> 1/cancel(2)x × cancel(2) = 6/5 × 2$

$=> x = 12/5$
