Solve the system of equations using matrices (row operations). \( \left\{\begin{array}{l}-x+y+z=-1 \\ -x+3 y-3 z=-9 \\ 4 x-3 y-6 z=0\end{array}\right. \) Select the correct choice below and fill in any answer boxes within your choice. A. The solution is \( x=\square, y=\square \), and \( z=\square \). (Simplify your answers.) B. The system has infinitely many solutions. The solution is \( x=\square, y=\square \), and \( z=z \). (Simplify your answers. Type expressions using \( z \) as the variable.) C. The system has infinitely many solutions. The solution is \( x=\square, y=y \), and \( z=z \). (Simplify your answer. Type an expression using \( y \) and \( z \) as the variables.) D. There is no solution.
