Solve: x+y=a+b and ax-by = a^2-b^2

Solve: x+y=a+b and ax-by = a^2-b^2

x+y=a+b –(i)

ax-by = a2-b2 –(ii)

Multiplying qequation (i) by b we get,

bx+by = ab+b2 — (iii)

Now adding equation (ii) and (iii) we get,

ax-by+bx+by =a2-b2 +ab+b2

⟹ x(a+b) = a(a+b)

⟹ x = a

Substituting the value of x in equation (i) we get,

a+y= a+b

⟹ y=b

Therefore Required Solutions are x = a and y =b.
