Answer:
5/x+3/y=30
25/x+15/y=150
9/x-5/y=2
27/x-15/y=6
adding,25/x+27/x=150+6=156
52/x=156
156x=52
x=52/156=1/3
5/x+3/y=30
15+3/y=30
3/y=30-15=15
15y=3
y=3/15=1/5

Answer:
x = 1/3 and y = 1/5
Step-by-step explanation:
Let, 1/x = a and 1/y = b
Therefore, 5a + 3b = 30 --------------- 1
9a - 5b = 2 ------------------2
Equation 1*5 + 2*3
52a = 156
a = 3, b = 5
x = 1/3, y = 1/5
