Question

(a-b)x+(a+b)y=a^2-2ab-b^2
(a+b)(x+y)=a^2+b^2

Solve the above linear pair .

Answer 1

Step-by-step explanation:

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

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

Substracting (2) from (1) we get

-2bx = -2ab

=2b² x = a + b

Subsitute x in equation (2) we get y = - 2ab / ( a + b).
