Por favor me ajudem!!! Obrigada
Escreva o sistema linear a seguir na forma matricial:
{
x+ 2y + 3z = 2
3x - 2y -z = 5
3x - 5y +3z = -4 }

Answer 1

Resposta passo a passo:

$\left\{\begin{array}{ccccc}x&+2y&+3z&=&2\\3x&-2y&-z&=&5\\3x&-5y&+3z&=&-4\end{array}\right\} \\\\\\Fo\´rma\ Matricial:$

$\left[\begin{array}{ccc}1&2&3\\3&-2&-1\\3&-5&3\end{array}\right] \ \ \ \left[\begin{array}{c}x\\y\\z\end{array}\right] \ \ \ =\ \ \ \left[\begin{array}{c}2\\5\\-4\end{array}\right]$
