Answer 1

Answer:

(a- b)x+(a+ b)y=a²-2ab-b²

⇒(a- b)x+(a+ b)y=a²-b² - 2ab

⇒ax- bx+ ay+ by =(a- b)(a + b)-2ab

⇒a(x+y) -b(x-y)=(a-b)(a+b)-2ab

⇒a(a+ b) -b(x-y)=(a- b)(a + b)-2ab                                     [From (i)]

⇒a²+ ab -b(x- y)=a²-b²-2ab

⇒b²+3ab -b(x- y)=0

⇒b(b + 3a) -b(x- y)=0

⇒b[b+3a-x+y]=0

(a+ b)(x+ y)=a² + b²

⇒(a+ b)(x+ y)=(a+ b)(a+ b)

⇒x+ y= a+ b........................(i)
