Answer
$ \left[\begin{array}{lll}
-4 & 4 & -1\\
-2 & -5 & 5
\end{array}\right]$
Work Step by Step
To subtract two matrices, they must have the same order.
The resulting matrix has elements obtained by subtracting the corresponding elements of the two matrices.
A and D are both $2\times 3 $ matrices (can be subtracted),
$D-A=\left[\begin{array}{lll}
-2-2 & 3-(-1) & 1-2\\
3-5 & -2-3 & 4-(-1)
\end{array}\right]$
=$ \left[\begin{array}{lll}
-4 & 4 & -1\\
-2 & -5 & 5
\end{array}\right]$
