3/x - 1/y = -9 …………...(a)
2/x + 3/y = 5 …………...(b)
Assume,
Let 1/x = s & 1/y = t
So,
3s - t = - 9 ………... (c)
2s + 3t = 5 …….... (d)
Now,
Multiply(c) by 3,
9s - 3t = - 27 …..…..(e)
Now,
Add (d) and (e),
11s = -22
s = -22/11
s = -2
Now,
Substituting value of s in (c)
3s - t = -9
3 × - 2 - t = -9
-6 - t = -9
-t = -9 + 6
-t = -3
t = 3
Here ,
1/x = s = -2
1/y = t = 3
Therefore,
x = -1/2 & y = 1/3
