Represent linear systems with matrix equations

The following system of equations is represented by the matrix equation A[xyz]=b\text{A}\left[\begin{array} {ccc} x \\ y \\ z \end{array} \right]=\vec{b}.
2x8y+z=53y+2z=108x9y+z=4\begin{aligned}2x-8y+z&=5 \\3y+2z&=-10 \\8x-9y+z&=4\end{aligned}
A=\textbf{A}=
b=\vec{b}=
Represent each row and column in the order in which the variables and equations appear.
