#1**+1 **

----------------------------

x = (x^2+y^2)

y = 2(x^2+y^2 ) from the first equation, this = 2x

Sub y = 2x in to the first equation

x = x^2 + 4x^2 re-arrange

5x^2-x = 0

x (5x-1) = 0 so x = 0 and .2 sub these values into the equation (red ones) to find the corresponding 'y' values.....
