`{:(x + y = a + b),(ax - by = a^(2) - b^(2)):}`

{:(ax - by = a^(2) + b^(2)),(x + y = 2a):}

{:(ax - by = a^(2) + b^(2)),(x + y = 2a):}

y = (ax + b) e^(-2x)

Solve for xandy: (x)/(a)+(y)/(b)=2,ax-by=a^(2)-b^(2)

(x)/(a)-(y)/(b)=0,ax+by=a^(2)+b^(2)

Solve: (x)/(a)+(y)/(b)=2,quad ax-by=a^(2)-b^(2)

Solve the following system of equations: x+y=a-b,quad ax-by=a^(2)+b^(2)

If y = ax ^(2) + b// x then x ^(2) y _(2) =

If x : a = y : b = z : c , then prove that (a^(2) + b^(2) + c^(2))(x^(2) + y^(2) + z^(2)) = (ax + by + cz)^(2)
