triciaal · Answer

suggestion pick 2 equations and decide which variable to eliminate
pick a different 2 equations and eliminate the same variable 
now you have 2 equations with the same 2 variables 
solve the simultaneous equations 
use thes values in either of the originals to find the value of the "eliminated" variable

ok.. so i pick the first 2 and i want to eliminate z... what next?
