Use a Matrix Approach to Solve the System $$\left( \begin{array} { r l } x - 3 y - 6 z & = - 20 \\6 x + 7 y - z & = - 45 \\5 x + y + 5 z & = 11\end{array} \right)$$

question 152

Short Answer

Use a matrix approach to solve the system. $$\left( \begin{array} { r l } x - 3 y - 6 z & = - 20 \\6 x + 7 y - z & = - 45 \\5 x + y + 5 z & = 11\end{array} \right)$$ If a system is inconsistent, so indicate. In those cases enter inconsistent .
