Use a Matrix Approach to Solve the System $\left(\begin{array}{c}x&-&4 y&-&z&=&9 \\6 x&+&y&-&3 z&=&-34 \\-5 x&+&7 y&+&2 z&=&-5\end{array}\right)$

question 207

Short Answer

Use a matrix approach to solve the system. $\left(\begin{array}{c}x&-&4 y&-&z&=&9 \\6 x&+&y&-&3 z&=&-34 \\-5 x&+&7 y&+&2 z&=&-5\end{array}\right)$ If a system is inconsistent, so indicate. In those cases enter inconsistent . Otherwise, enter your answer in the form ( x , y ).
