Answer
$\begin{bmatrix}
-3 & 9 & -7
\end{bmatrix}$
Work Step by Step
Adding each corresponding elements of the matrices, the given matrix expression, $
\begin{bmatrix}
3 & 5 & -8
\end{bmatrix}
+
\begin{bmatrix}
-6 & 4 & 1
\end{bmatrix}
,$ results to
\begin{align*}
&
\begin{bmatrix}
3+(-6) & 5+4 & -8+1
\end{bmatrix}
\\\\&=
\begin{bmatrix}
3-6 & 5+4 & -8+1
\end{bmatrix}
\\\\&=
\begin{bmatrix}
-3 & 9 & -7
\end{bmatrix}
.\end{align*}
Hence, the given matrix operation results to $
\begin{bmatrix}
-3 & 9 & -7
\end{bmatrix}
.$
