Question

(a-b)x+(a-b)y=a-2ab-b²
(a+b)(x+y) =a²+b² using cross multiplication​

Answer 1

Answer:

x=a+b

y=-2ab/a+b

Step-by-step explanation:

x/(a+b)(a²+b² ) ;(a-b)(a-2ab-b²)=

-y/(a-b)(a-2ab-b²);(a+b)(a²+b² )=

-1/(a-b)(a+b);(a+b)(a+b)

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

x/(a+b)2b(b+a) =-y/4ab²=-1/2b(a+b)

x=a+b

y=-2ab/a+b
