2x + y - (x + y) = 3z - 6z 
--------------------------------------------------------
<span>x = -3z </span>
------------------------------------------
<span>(-3z, 9z) </span>
 ----------------------------------
<span>(x,y,z) = (-3z, 9z, z) 
</span>--------------------------
<span>x = -3z, y = 9z
---------------------
There for the answer is </span><span>(-3z, 9z) </span>
