Use a Matrix Approach to Solve the System $$\left( \begin{array} { c } - 5 x + y + 2 z = 21 \\6 x + 8 y - z = - 72 \\x + 2 y + z = - 9\end{array} \right)$$

question 166

Short Answer

Use a matrix approach to solve the system. $$\left( \begin{array} { c } - 5 x + y + 2 z = 21 \\6 x + 8 y - z = - 72 \\x + 2 y + z = - 9\end{array} \right)$$ If a system is inconsistent, so indicate. In those cases enter inconsistent . Otherwise, enter your answer in the form ( x , y ).
