Perhaps HoldForm[X[x, y, z]] == X[x, y, z] // TraditionalForm?

Your rules simply don't match your expression. You'd have to rearrange your expression into the correct form to get the rules to match. Mathematica will not do this automatically for you.

@dionys I'm not sure why you would expect it to work with negative numbers though. There's nothing in the algorithm that will give you a complex number.

comment Faster way to use Solve in a multiple parameters function
FindRoot finds just a single root numerically. So it will vary depending on where you start it. One technique might be to do a coarse grid with the full Solve. Then use those as starting points for a finer FindRoot grid.
