Use a Matrix Approach to Solve the System $$\left( \begin{array} { r } 2 x + 2 y - z = 8 \\3 x + 3 y + 4 z = 1 \\5 x + y + 4 z = 7\end{array} \right)$$

question 136

Short Answer

Use a matrix approach to solve the system. $$\left( \begin{array} { r } 2 x + 2 y - z = 8 \\3 x + 3 y + 4 z = 1 \\5 x + y + 4 z = 7\end{array} \right)$$ If a system is inconsistent, so indicate. In those cases enter inconsistent . Otherwise, enter your answer in the form ( x , y ).
