You can also add equations 1 and 2, eliminating z from those two as well.  That will give you a second equation in x and y only.  That leaves you with a 2X2 system.  As it happens, you will then be able to add the two 2-variable equations to eliminate y.  From there you solve the single variable equation in x, substitute the value for x into either of the 2-variable equations, solve for y, then substitute x and y into any one of the original equations and solve for z.
