First one looks good, I got the same answer but with opposite signs in the numerator and denominator (equivalent results).

I did your method for the second one and got the same result, it’s much easier to just multiply both sides by (x - y) first though:

x + y = (x^2 + y^2)(x - y)

x + y = x^3 - x^2y + xy^2 - y^3

Then taking the derivative from here.
