Answer
$\begin{bmatrix}
9
\\
-2
\end{bmatrix}$
Work Step by Step
Subtracting each corresponding elements of the matrices, the given matrix expression, $
\begin{bmatrix}
3
\\
5
\end{bmatrix}
-
\begin{bmatrix}
-6
\\
7
\end{bmatrix}
,$ results to
\begin{align*}
&
\begin{bmatrix}
3-(-6)
\\
5-7
\end{bmatrix}
\\\\&=
\begin{bmatrix}
3+6
\\
5-7
\end{bmatrix}
\\\\&=
\begin{bmatrix}
9
\\
-2
\end{bmatrix}
.\end{align*}
Hence, the given matrix operation results to $
\begin{bmatrix}
9
\\
-2
\end{bmatrix}
.$
