Thanks so much for the help! I really appreciate it!

Ok, I don't know what I was doing before but I think I understand it now. Maybe. If y=0, then x=12 or +/-sqrt(13)---> (12,0) and (sqrt(13),0) another possibility if y=/=0 would be (x, +/-sqrt(13-x^2)) right? EDIT: (because I made a stupid mistake above) y=0, x=1,3,-4 when y=0 the...

This gets more confusing the more I think about it... From the condition (13-x^2-y^2)=0, I got x=+/- sqrt(13-y^2), then plugging x back into (13-x^2-y^2)=0 means that y=0 and x=sqrt(13)?? Or am I going in circles?

So the system is inconsistent?
