Answer 1

-3 e 8

So fazer equacao ;)

Answer 2

$A=\left[\begin{array}{ccc}a+1&b-2&3\\3&4&0\end{array}\right]$

$B=\left[\begin{array}{ccc}-2&6&3\\3&4&0\end{array}\right]$

$A=B$

$\left[\begin{array}{ccc}a+1&b-2&3\\3&4&0\end{array}\right]=\left[\begin{array}{ccc}-2&6&3\\3&4&0\end{array}\right]$

$a+1=-2~~\Rightarrow~~a=-2-1~~\Rightarrow~~\boxed{a=-3}$.

$b-2=6~~\Rightarrow~~b=6+2~~\Rightarrow~~\boxed{b=8}$.
