Given the system of equations:

` { ( 2x-3y-9z = 31), ( x+3z = -7), ( -3x+y-4z = 6) :} `

(a) Determine the type of system: inconsistentdependent

(b) If your answer is dependent in (a), find the complete solution.
Write `x`, `y` as functions of `t`, where `z=t`.

If your answer is inconsistent, write DNE for all three variables.

`x=`  
`y=`  
`z=`
