Use a Matrix Approach to Solve the System $$\left( \begin{array} { c c c c } x - 5 y & = & 15 \\5 x + 4 y & = & - 41\end{array} \right)$$

question 17

Short Answer

Use a matrix approach to solve the system. $$\left( \begin{array} { c c c c } x - 5 y & = & 15 \\5 x + 4 y & = & - 41\end{array} \right)$$ If a system is inconsistent, so indicate. In those cases enter inconsistent . Otherwise, enter your answer in the form ( x , y ).
