Solution
5x + `8/y` = 19 ....(1)
3x - `4/y` = 7 .....(2)
Multiplying equation (2) by 2, We get,
6x - `8/y` = 14 ......(3)
Adding (1) and (3), We get,
5x + `8/y` = 19
+ 6x - `8/y` = 14
11x = 33
x = 3
Substituting x = 3 in equation (1), We get
5(3) + `8/y` = 19
15 + `8/y` = 19
`8/y` = 19 - 15
y = `8/4`
y = 2
