If x and y are irrational numbers, and x/y and xy are both rational, is x+y rational as well?

If the answer is always yes, why? If sometimes yes and sometimes no can you provide example pairs of x and y to show that sometimes x + y is rational and sometimes it isn't. If the answer is always no, can you prove it?
