I didn't try a generalization because I didn't think it was necessary. Selecting a subset of cases is fine provided there some way to reduce the general case to your two specific cases. Or perhaps we could go in the reverse direction. Is there a way to generalize your specific cases to the more general one where no additional assumptions on x, y, and z need to be made? I do not know myself; this is a genuine question. Quote:I might return to this problem, but not anytime soon. Meanwhile the solutions I have presented so far should be considered wrong, invalid and useless. There is nothing mathematically wrong about your two specific solutions with the additional assumptions about x, y, and z. Graph 3D  QPI  SolveSys
