I want to solve three equations with three unknowns and display the solution on a 3D graph with two points - the roots of the equation.
Help please!

Findroot() or roots() could solve three unknown systems.
About plotting, I simply wrote equations according to solving of z.

Is there a way to use CreateMesh() for single line xyz equations?
x^2+y^2+z^2-2^2 creates a sphere in 3dplot, a finer mesh can look better.
But I don't know how to convert an equation to CreateMesh().
I am asking if it is doable of course, if they are two different thing it is ok.
A simple, short but inclusive tutorial would be beneficial.

Like in the attached? (Though I confess it was a "suck it and see" approach as I don't fully understand the 3D graphing!)

Not really, my question is different.
You can make any object with CreateMesh().
You can make sphere, plane, cone, cube, etc with mesh.
I ask for a method converting a xyz function to CreateMesh() matrix.
If there is any of course.

Hi Overlord. If you can isolate some of the x, y or z variables, you can use this. If not, Viacheslav develops a 3D implicit plot codes for mathcad, you can see that somewhere in the mathcad forum.

The dots on the graphs above are a sign of my code being used.

This is only possible for simple cases if the function is easily parameterizable.
