solve the following pair of equation ​

Answer 1

hey mate Hope it will you

Answer 2

Solñ: 5/x+y-2/x-y=-1...............................(1)

15/x+y+7/x-y=10......................................(2)

Let,

1/x+y=a, 1/x-y=b

(1)»5a-2b=-1.........(3)

(2)»15a+7b=10.....(4)

(1)×3»15a-6b=-3........(5)

(4)-(5)»13b=13

»b=13/13=1

(3)»5a-2×1=-1

»5a=-1+2

»a=1/5

:. 1/x+y=a

»1/x+y=1/5

»x+y=5.....(6)

Again,

1/x-y=b

»1/x-y=1

»x-y=1........(7)

(6)+(7)»2x=6

»x=6/2=3

(6)»3+y=5

»y=5-3=2..........I hope you're helpful ........
