Question

Solve 10/x+y + 2/x-y=4 , 15/x+y=2
​

Answer 1

Step-by-step explanation:

10/x+y + 2/x-y=4

[10(x-y) +2(x+y)]/(x²-y²)=4

(10x-10y+2x+2y)/(x²-y²)=4

(12x-8y)/(x²-y²)=4

12x-8y=4x²-4y²

4x²-12x-4y²+8y=0

4(x²-3x-y²+2y) =0

x²-3x-y²+2y=0....(1)

15/x+y=2

2(x+y)=15

x+y=15/2

x=(15/2)-y

x=(15-2y)/y.......(2)

from (1)

x²-3x-y²+2y=0

[(15-2y)/y]²-3[(15-2y)/y]-y²+2y=0

after that you can solve

Answer 2

x = 33/8

y = 27/8
