(a-b)x + (a+b)y = a^2 - 2ab - b^2 ---(1)
(a+b)(x+y) = a^2 + b^2
(a+b)x + (a+b)y = a^2 + b^2 ---(2)
(2)-(1)
2bx = 2ab + 2b^2
x = a + b
from(2)
(a+b) (a+b+y) = a^2 + b^2
(a+b)^2 + (a+b)y = a^2 + b^2
a^2 + 2ab + b^2 + (a+b)y = a^2 + b^2
y = -2ab / (a+b)

x= a+b
y= - (2ab)/(a+b)
-[ ax-bx+ay+by=a^2-2ab-b^2]
[ ax+bx+ay+by=a^2+b^2]
+--------------------------------------
x=a+b
