Answer

The solution is $\frac{1}{13}$

Work Step by Step

y-$\frac{3}{13}$=-$\frac{2}{13}$ Add $\frac{3}{13}$ to both sides y- $\frac{3}{13}$+$\frac{3}{13}$=-$\frac{2}{13}$+$\frac{3}{13}$ y= $\frac{-2+3}{13}$ y=$\frac{1}{13}$ The solution is $\frac{1}{13}$ Check Replace x with $\frac{1}{13}$ y-$\frac{3}{13}$=-$\frac{2}{13}$ Replace y with $\frac{1}{13}$ $\frac{1}{13}$-$\frac{3}{13}$ =-$\frac{2}{13}$ -$\frac{2}{13}$=-$\frac{2}{13}$
