$-4A-B^T=\begin{pmatrix}
11 & -18 & -9& -24\\
4 & 2 & -17 & -1
\end{pmatrix}$
Work Step by Step
$-4A-B^T$
$=\begin{pmatrix}
8 & -16 & -8 & -24\\
4 & 4 &-20 & 0
\end{pmatrix}-\begin{pmatrix}
-3 & 2 & 1 & 0\\
0 & 2 & -3 & 1
\end{pmatrix}$
$=\begin{pmatrix}
11 & -18 & -9& -24\\
4 & 2 & -17 & -1
\end{pmatrix}$
