Question

The value of $x$ satisfying the equation $x-\frac{7}{5}=\frac{13}{5}$ is___

Answer 1

$x-\frac{7}{5}=\frac{13}{5}$
We need to get rid of $-\frac{7}{5}$ from the left side of the equation. So, we add $\frac{7}{5}$ on both sides.
$x-\frac{7}{5}+\frac{7}{5}=\frac{13}{5}+\frac{7}{5}$
$x=\frac{20}{5}$
$x=4$
