- Running mma 2.1 on a Sparc-2, I input the following:
-
- Solve[{Sqrt[x]+y==11,x+Sqrt[y]==7},{x,y}].
-
-
-
- this results in four roots. substituting the result in
- Sqrt[x]+y (or Sqrt[y]+x), only two of the roots are
- correct. the other two are numbers like 14.nnn and 17.nnn.
-
-
- if someone has time, please see if your setup has any
- difficulty here.
-
- thanks.
