5/x-3/y=1
(5y-3x) /xy=1
5y-3x=xy ......(1)
similarly
2/x+5/y=19
(2y+5x)/xy=19
2y+5x=19xy .........(2)
multiplying (1) by 2 and (2) by 5 we get,
10y-6x=2xy .........(3)
10y+25x=95xy .........(4)
subtracting (4) from (3) we get
-31x=-93xy
31x=93xy
31=93y
y=1/3 (Ans)
substituting the value of y in (1) we get
x=1/2 (Ans)
