Let the following equations system for x, y Reals
Mathematica 6.0.1 yields no solution. But the solutions exist. They
are four solutions
Mathematica first simplifying y/(9y) -> 1/9 and it compare with 0/(5x) -
> and yiels False and it stops the process. Is this correct?.
In my opinion, the correct process would be
5xy=0 ----> x=0 or y=0
and substitution in the second equation.
