The method that I would choose is the "elimination" method.  This may not have been the method you or others would choose.

Add the last two equations getting: 2x -5y + z = -25.  Now subtract this equation from the first original equation:
    2x + y + z = -7
-) 2x  -5y +z = -25
------------------
          6y         = 18   or y = 3   this has solved the problem to one of its variables.

I chose the elimination method because it is the simplest for me.
