Answer 1

Resposta:

Explicação passo-a-passo:

$\left[\begin{array}{cc}2&0\\-1&3\end{array}\right] -\left[\begin{array}{cc}1&5\\4&-2\end{array}\right] -3.\left[\begin{array}{cc}-1&4\\0&-2\end{array}\right] =$

$\left[\begin{array}{cc}2&0\\-1&3\end{array}\right] -\left[\begin{array}{cc}1&5\\4&-2\end{array}\right] -.\left[\begin{array}{cc}3.(-1)&3.4\\3.0&3.(-2)\end{array}\right] =$$\left[\begin{array}{cc}2-1&0-5\\-1-4&3-(-2)\end{array}\right] -\left[\begin{array}{cc}-3&12\\0&-6\end{array}\right] =$

$\left[\begin{array}{cc}1&-5\\-5&5\end{array}\right] -\left[\begin{array}{cc}-3&12\\0&-6\end{array}\right] =$

$\left[\begin{array}{cc}1-(-3)&-5-12\\-5-0&5-(-6)\end{array}\right]=$

$\left[\begin{array}{cc}4&-17\\-5&11\end{array}\right]$
