x/a+y/b-(a+b) = 0……………..(1).

x/a^2+y/b^2–2 = 0…………………(2).

x/{-2/b+(a+b)/b^2} = y/{-(a+b)/a^2+2/a} = 1/{1/ab^2–1/a^2b}.

x/{(a-b)/b^2} = y/{(a-b)/a^2} = 1/{(a-b)/a^2.b^2}.

x.b^2 = y.a^2 = a^2.b^2.

x= a^2.b^2/b^2 =a^2. Answer.

y =a^2.b^2/a^2 = b^2. Answer.

Answer:

x /a +y / b= a  +  b , x/ a² + y/b²= 2.

a1= 1/a, b1= 1/b, c1= -(a+b)= -a-b

a2= 1/a² , b2= 1/b² , c= -2

    x                       y                       1

-----------   =   -----------------     =    -------------

b1      c1        c1           a1           a1        b1

b2      c2       c2           a2           a2       b2

      x                          y                        1

-----------------   =    -------------------  =   ---------

1/b    - a-b           -a-b     1/a         1/a    1/b

1/b²   -2               -2       1/a²         1/a²  1/b²

    x                     y                            1

----------- =   ---------------  =    -----------------

-2/b +(a+b)/b²   -(a+b)/a² + 2/a   1/ab² -1/ba²

 x b²         a² y               a² b²

---------   = --------  =     ----------

a - b        a - b              a - b

x = a²    and  y = b²      

Hence the value of x = a² & y = b²
