Reinserting the variables, the system is now:














                             Equation (9) can be solved for z.
















           Substitute                              into equation (8) and solve for y.


























           Substitute                               into equation (7) and solve for x.




























        The solution is
   8   9   10   11   12   13   14   15   16   17   18
