Hello!
In Mathematica 5.1 I get the following result from Reduce:
Reduce[{x^2 - y == 2, x + y == 0}, {x, y}]
(x == -2 || x == 1) && y == -x
Sincerely, I preferred the output of version 4.2:
x==-2 && y==2 || x==1 && y==-1
To recover this good old form in 5.1 I have to Reduce[] twice:
Reduce[Reduce[{x^2 - y == 2, x + y == 0}, {x, y}]]
I think wri should work on this for the next version.
Best regards,
Gianluca Gorni
