||||||||||x y z
det([2 13 -7])
||||||||||27 11 13
The answer:
246x-329z-215
Note: y is missing.
Well, if put the x g z, instead of x y z, then the g will not be missed.
So what's wrong with y?

It seems you assigned number "1" to "y" variable. You should clear variables if you want to calculate symbolically.
The answer from my classpad is 246x-215y-329z.
