If $\displaystyle$$\displaystyle \frac{3}{x+y} + \frac{2}{x-y}$ = -1 and $\displaystyle$$\displaystyle \frac{1}{x+y} - \frac{1}{x-y} = \frac{4}{3}$ then $\displaystyle (x, y)$ is:

$\displaystyle \frac{2x+5}{10} + \frac{3x+10}{15} = 5$, find $\displaystyle x$

The values of $\displaystyle x$ and $\displaystyle y$ satisfying the equations $\displaystyle$$\displaystyle \frac{3}{x+y} + \frac{2}{x-y} = 3$ and $\displaystyle$$\displaystyle \frac{2}{x+y} + \frac{3}{x-y} = \frac{23}{3}$ given by
