33Junior MemberI put 2-sqrt(2) also, but that's a complete guess.

I can't remember if I put 4 or 16 for the last one, but I solved it by multiplying the first equation by 3 and then adding the two equations together. The first system of equations where x and y were NOT under radicals had nothing to do with the question I think.
