All the sides add like a rectangle with two sides measuring 4 and two measuring 2 so you would add 4+4+2+2=12
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>
