Answer:

As x + y = a + b, and

ax - by = a^2 - b^2

\Rightarrow ax - by = (a+b)(a-b)\\\Rightarrow ax - by = (x + y) (a-b) [\because x + y = a + b]

Solving, we get

ay-bx=0    ...(1)

Now, multiply given equation with \text {a},

Now, given equation becomes as

ax+ay=a^2+ab      ...(2)

Solving Eqns. (1) and (2), we get

x = a \text { and } y = b
