Given the system of equations! \( \left\{\begin{array}{l}2 x-3 y-9 z=6 \\ x+3 z=-6 \\ -3 x+y-4 z=12\end{array}\right. \) (a) Determine the type of system: O dependent inconsistent (b) If your answer is dependent in (a), find the complete solution. Write \( x, y \) as functions of \( z \). If your answer is inconsistent, write DNE for all three variables. \( x=\square \) \( y=\square \) \( z=\square \)
