Fun little math problem

I'm sure I have the terminology wrong there, but the x+y=x*y has a solution at (0,0) and x-y-y/x = epsilon as x,y approach 0 (for the right small values of x&y)

Nice little problem. Thanks for posting! It reminds me of another one, worked-out allegedly in half a minute by a 14-year old student, about one hundred years ago:

\(\left \{ _{\sqrt{y}+x=11}^{\sqrt{x}+y=7} \right.\)

No ordinary student, though.
