Answer 1

Resposta:

Explicação passo a passo:

$\left[\begin{array}{ccc}a&1\\b&3\\a+b&4\end{array}\right] =\left[\begin{array}{ccc}4&c\\7&c+d\\11&d+e\end{array}\right]$

   $Por\:comparac\tilde{a}o\:temos...$

 $a=4$

 $c=1$

 $b=7$

$c+d=3$

$1+d=3$

$d=3-1$

$d=2$

$d+e=4$

$2+e=4$

$e=4-2$

$e=2$

$Portanto...$

$a=4\\b=7\\c=1\\d=2\\e=2$
