Question

Preciso do cálculo
Please​

Answer 1

Explicação passo-a-passo:

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

$B=\left[\begin{array}{ccc}5&1&3\\-2&0&2\end{array}\right]$

$(X+A) = B^T$ pois,  $(X+A)^T = B$

$B^T=\left[\begin{array}{ccc}5&-2\\1&0\\3&2\end{array}\right]$

$\left[\begin{array}{ccc}a_{11} &a_{12} \\a_{21} &a_{22}\\a_{31}&a_{32}\end{array}\right] + \left[\begin{array}{ccc}1&2\\-1&0\\4&3\end{array}\right] =\left[\begin{array}{ccc}5&-2\\1&0\\3&2\end{array}\right]$

        X                      A                    $B^T$

$X=\left[\begin{array}{ccc}4&-4\\2&0\\-1&-1\end{array}\right]$
