You are very welcome Nathan. Long ago they were called Solving Systems of Equations in three unknowns those being x, y and z. Pretty much like 2 equations in two unknowns x and y with Substitution, Elimination, or Graphically. Elementary Row Operations.

Also if you are familiar and comfortable with 3D graphing you could check the systems on a graphing calculator (one that is capable of 3D graphing)
