2x-3-x=-\frac{2}{5}
Subtract x from both sides.
x-3=-\frac{2}{5}
Combine 2x and -x to get x.
x=-\frac{2}{5}+3
Add 3 to both sides.
x=-\frac{2}{5}+\frac{15}{5}
Convert 3 to fraction \frac{15}{5}.
x=\frac{-2+15}{5}
Since -\frac{2}{5} and \frac{15}{5} have the same denominator, add them by adding their numerators.
x=\frac{13}{5}
Add -2 and 15 to get 13.
