por favor!!! e pra hoje!!!​

Answer 1

Resposta:

$x = \left[\begin{array}{ccc}5&5\\3&2\\\end{array}\right]$

Explicação passo-a-passo:

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

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

$\left[\begin{array}{ccc}5&6\\2&2\\\end{array}\right] = x + \left[\begin{array}{ccc}0&1\\-1&0\\\end{array}\right]$

$x = \left[\begin{array}{ccc}5&5\\3&2\\\end{array}\right]$
