For two matrices to be equal, their corresponding elements must be equal. Thus, $x = -1$ and $y = -5$.

Find X and Y [6xy−8]=[6−1−5−8]\left[ \begin{array} { c c } 6 & x \\y & - 8\end{array} \right] = \left[ \begin{array} { c c } 6 & - 1 \\- 5 & - 8\end{array} \right][6y​x−8​]=[6−5​−1−8​]

Find X and Y $\left[ \begin{array} { c c } 6 & x \\y & - 8\end{array} \right] = \left[ \begin{array} { c c } 6 & - 1 \\- 5 & - 8\end{array} \right]$
