Answer 1

Resposta:

$\textsf{Leia abaixo}$

Explicação passo a passo:

$\textsf{A} = \begin{bmatrix}\cancel2&\cancel x + 1&\cancel1\\\cancel3&\cancel5&\cancel y - 2\\\cancel |\:z\:|&\cancel0&\cancel6\end{bmatrix}\:\:\:\:\:\:\textsf{B} = \begin{bmatrix}\cancel2&\cancel7&\cancel1\\\cancel3&\cancel5&\cancel9\\\cancel 4&\cancel0&\cancel6\end{bmatrix}$

$\mathsf{x + 1 = 7}$

$\mathsf{x = 7 - 1}$

$\boxed{\boxed{\mathsf{x = 6}}}$

$\mathsf{y - 2 = 9}$

$\mathsf{y = 9 + 2}$

$\boxed{\boxed{\mathsf{y = 11}}}$

$\mathsf{|\:z\:| = 4}$

$\boxed{\boxed{\mathsf{z = \pm\:4}}}$
