-\frac{1}{2}w-\frac{3}{5}-\frac{1}{5}w=0
Subtract \frac{1}{5}w from both sides.
-\frac{7}{10}w-\frac{3}{5}=0
Combine -\frac{1}{2}w and -\frac{1}{5}w to get -\frac{7}{10}w.
-\frac{7}{10}w=\frac{3}{5}
Add \frac{3}{5} to both sides. Anything plus zero gives itself.
w=\frac{3}{5}\left(-\frac{10}{7}\right)
Multiply both sides by -\frac{10}{7}, the reciprocal of -\frac{7}{10}.
w=\frac{3\left(-10\right)}{5\times 7}
Multiply \frac{3}{5} times -\frac{10}{7} by multiplying numerator times numerator and denominator times denominator.
w=\frac{-30}{35}
Do the multiplications in the fraction \frac{3\left(-10\right)}{5\times 7}.
w=-\frac{6}{7}
Reduce the fraction \frac{-30}{35} to lowest terms by extracting and canceling out 5.
