Use matrices to solve the system of equations (if possible).Use Gaussian elimination with back-substitution or Gauss-Jordan elimination. $$\left\{ \begin{aligned}
4 x - 9 y - 9 z & = - 74 \
6 x + 8 y - 2 z & = - 22 \
6 x - y + 9 z & = 4
\end{aligned} \right.$$
A)x = 5, y = -2, z = 4
B)x = 2, y = 5, z = -4
C)x = -5, y = -2, z = 4
D)no solution
E)x = -5, y = 2, z = 4
