-\frac{2}{5}x=120
Combine \frac{3}{5}x and -x to get -\frac{2}{5}x.
x=120\left(-\frac{5}{2}\right)
Multiply both sides by -\frac{5}{2}, the reciprocal of -\frac{2}{5}.
x=\frac{120\left(-5\right)}{2}
Express 120\left(-\frac{5}{2}\right) as a single fraction.
x=\frac{-600}{2}
Multiply 120 and -5 to get -600.
x=-300
Divide -600 by 2 to get -300.
