Question

Find x and y


(a-b)x+(a+b)y=a2-2ab-b2
(a+b)+(x+y)=a2+b2

Answer 1

Hey here is your answer...

(a-b)x+(a+b)y=a²-2ab-b²
(a+b)(x+y)=a²+b².............(1)

(a+b)x+(a+b)y=a²+b²

(a-b)x-(a+b)x=(a²-2ab-b²)-(a²+b²).........(2)

(a-b-a-b)x=-2ab-2b²-2bx=-2b(a+b)

x=a+b

(a-b)(a+b)+(a+b)y+a²-2ab-b²

a²-b²+(a+b)y=a²-2ab-b²

(a+b)y=-2ab
