    Step-by-step explanation:

    x/a + y/b = a+b 

    ⇒y/b = a + b – x/a     ……………… i 

    x/a² + y/b² = 2 …………….ii

    ⇒x/a² + y/b x1/b = 2

    ⇒x/a² + a+b/b – x/ab = 2                 puttting i 

    ⇒x(b-a)/a²b = (b-a)/b

    ⇒x = a²

    so x = a² 

    using ii we get 

    y = b²

    so x=a² and y=b² ANSWER
