Evaluate the expression $LaTeX: \displaystyle 5 A - B - 5 C$
$LaTeX: A = \left[\begin{matrix}-5 & 6 & -3\\1 & 8 & 8\end{matrix}\right],\quad\quad B = \left[\begin{matrix}-3 & -2 & 4\\-9 & 8 & 5\end{matrix}\right], \text{ and } \quad C = \left[\begin{matrix}9 & -3 & -3\\-4 & 7 & 5\end{matrix}\right].$

The sum is $LaTeX: \displaystyle \left[\begin{matrix}-67 & 47 & -4\\34 & -3 & 10\end{matrix}\right]$ .
