Answer :
For this problem we have the following equation given:
[tex]-\frac{1}{2}w-\frac{3}{5}=\frac{1}{5}w[/tex]For this case we can add 1/w in both sides of the equation and we got:
[tex]-\frac{3}{5}=\frac{1}{2}w+\frac{1}{5}w=\frac{7}{10}w[/tex]Finally we can find the solution for w multiplying by 10/7 both sides of the equation and we got:
[tex]w=\frac{10}{7}\cdot(-\frac{3}{5})=-\frac{30}{35}=-\frac{6}{7}[/tex]And the final solution would bew -6/7
