	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.
