Step-by-step explanation:
8/x - 5/y = 34
3/x - 2/y = 13
let 1/x = a ; and 1/y = b
the equations will be
8a - 5b = 34. equ (1)
3a - 2b = 13 equ (2)
multiply equation (1) with 2 and equation (2) with 5
16a - 10b = 68 equ (3)
15a - 10b = 65 equ (4)
subtract (3) - (4)
we get
a = 3
substitute a = 3 in equ (2)
3(3) - 2b = 13
9 - 2b = 13
-2b = 13 - 9
- 2b = 4
- b = 4/2
- b = 2
b = - 2
a = 1/x = 3
x = 1/3
b = 1/y = -2
y = - 1/2
Hope you get your answer
