20.give that (a-b)x+(a+b)y=a^2-2ab-b^2--------------equation-1
(a+b)x+(a+b)y=a^2+b^2--------------------------------------equation-2
substrating (2) from (1) we get
-sbx=-2ab-2b^2
x=a+b
substitute x in equatin -2
y=-2ab/a+b
(a+b)x+(a+b)y=a^2+b^2--------------------------------------equation-2
substrating (2) from (1) we get
-sbx=-2ab-2b^2
x=a+b
substitute x in equatin -2
y=-2ab/a+b
