Solution 1

First, we need to multiply the first matrix by 6:

6[132241]=[6181212246]6\begin{bmatrix}1&3&2\\-2&4&-1\end{bmatrix} = \begin{bmatrix}6&18&12\\-12&24&-6\end{bmatrix}

Then, we add the resulting matrix to the second matrix:

$\begin{bmatrix}6&18&12\-12&24&-6\end{bmatrix} + \begin{bmatrix}5&7&-1\6&-4&7\end{bmatrix} =
