Question

Solve the equation
x+y=a-b
ax+by=a2-b2

Answer 1

put me as brilliant plz

Solution for x and y.    

bx / a ay / b = a2 + b2 ----- eq 1

x+y = 2ab ------- eq 2

from eq1 ----- b2x + a2 ab = a2 + b2

→ b2 x a2y = a3 b - a2y

→ b2 (x-ab) = a2 (ab - y)

from eq2 ----- b2 (x - x/2 + y/2)

= a2 (x/2 + y/2 - y)

→ b2 ( x/2 - y/2) = a2 (x/2 + y/2)

→ b2 x  - b2y = a2x - a2y

→ x = y --------

put the value of x in eq2 ----- 2y = 2ab.
