Use Gaussian elimination to solve the system of equations.
$$\begin{array} { l }
6 x + 9 y + 2 z = 90 \
- 8 x + 4 y + 4 z = - 40 \
18 x + 3 y - 4 z = 150
\end{array}$$
A) $( 12,4,10 )$

B) $( - 4 , - 12,10 )$

C) $\left\{ \frac { 180 + 7 t } { 24 } , \frac { 60 - 5 t } { 12 } , t \right\}$, for $t$ any real number

D) $( 4,10 , - 12 )$
