Firstly we would approach the question by looking at the question by attempting to group together the x terms to solve for x. By looking at the question we can see that the x terms are the denominators so...

Firstly we need to realise that equation 1 (x^2 + y^2 = 9) does not factorise. So once realising this, we must rearrange equation 2 (x + y = 2) so that y = 2 - x. Now we substitute (y = 2 - x) into equati...
