Answer
$\begin{bmatrix}
1.5 & -1.9
\\
0 & 4.6
\end{bmatrix}
-
\begin{bmatrix}
8.3 & -3.2
\\
2.1 & 5.6
\end{bmatrix}
=
\begin{bmatrix}
-6.8 & 1.3
\\
-2.1 & -1
\end{bmatrix}$
Work Step by Step
Adding/subtracting the corresponding elements, the given matrix expression $
\begin{bmatrix}
1.5 & -1.9
\\
0 & 4.6
\end{bmatrix}
-
\begin{bmatrix}
8.3 & -3.2
\\
2.1 & 5.6
\end{bmatrix}
,$ simplifies to
\begin{align*}
&
\begin{bmatrix}
1.5-8.3 & -1.9-(-3.2)
\\
0-2.1 & 4.6-5.6
\end{bmatrix}
\\\\&=
\begin{bmatrix}
-6.8 & 1.3
\\
-2.1 & -1
\end{bmatrix}
.\end{align*}
Hence, $
\begin{bmatrix}
1.5 & -1.9
\\
0 & 4.6
\end{bmatrix}
-
\begin{bmatrix}
8.3 & -3.2
\\
2.1 & 5.6
\end{bmatrix}
=
\begin{bmatrix}
-6.8 & 1.3
\\
-2.1 & -1
\end{bmatrix}
$.
