solving equations by the method of elimination

$\frac{a}{x}+\frac{b}{y}=\frac{a}{2}+\frac{b}{3}\phantom{\rule{thickmathspace}{0ex}}\phantom{\rule{thickmathspace}{0ex}}\phantom{\rule{thickmathspace}{0ex}}\dots (i)$

$x+1=y\phantom{\rule{thickmathspace}{0ex}}\phantom{\rule{thickmathspace}{0ex}}\phantom{\rule{thickmathspace}{0ex}}\dots (ii)$

We have to solve for x and y, only this time using the method of elimination.

From equation $(ii)$, we get,

$\frac{1}{x+1}=\frac{1}{y}\Rightarrow \frac{b}{x+1}=\frac{b}{y}\phantom{\rule{thickmathspace}{0ex}}\phantom{\rule{thickmathspace}{0ex}}\phantom{\rule{thickmathspace}{0ex}}\dots (iii)$

Subtracting $(iii)$ from $(i)$, we get,

$\frac{a}{x}+\frac{b}{y}-\frac{b}{y}=\frac{a}{2}+\frac{b}{3}-\frac{b}{x+1}$

$\Rightarrow \frac{a}{x}=\frac{a}{2}+\frac{b}{3}-\frac{b}{x+1}$

After that,I really cannot find anything to do.I have taken quite a few other routes, but have hit nothing but dead ends. At this a point a little hint will be appreciated.
