Answer 1

Heya mate!

Here is your Answer!

Make sure to mark it BRAINLIEST!

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   Putting 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
