QuestionWrite the system of equations as an augmented matrix. $$\left\{\begin{array}{l} -3 x+6 y-6 z=-54 \\ -2 x+3 y-7 z=-106 \\ -7 x-3 y-7 z=-272 \end{array}\right.$$
Reduce the matrix into reduced row echelon form.
Identify the solution to the original system of equations. $$(x, y, z)=(4,-1,6) \times$$
