Answer 1

Bom dia!


$\begin{bmatrix}a11&a12\\a21&a22\\ a31&a32\end{bmatrix}$ 

$\mathit{a11}\rightarrow1+2*1\rightarrow1+2=3$
$\mathit{a12}\rightarrow1+2*2\rightarrow1+4=5$
$\mathit{a21}\rightarrow2+2*1\rightarrow2+2=4$
$\mathit{a22}\rightarrow2+2*2\rightarrow2+4=6$
$\mathit{a31}\rightarrow3+2*1\rightarrow3+2=5$
$\mathit{a32}\rightarrow3+2*2\rightarrow3+4=7$

$\begin{bmatrix}a11&a12\\a21&a22\\a31&a32\end{bmatrix}$ = $\begin{bmatrix}3&5\\4&6\\5&7\end{bmatrix}$
