Question

The system

x+2y=5
3y+z=1
2x-z=8

can be represented by a matrix equation. What will be the dimensions of the coefficient matrix? Explain.

Thank you:)

Answer 1

\[\left[\begin{matrix}1 & 2 & 0\\ 0 & 3 & 1\\ 2 & 0 & -1\end{matrix}\right]\ \left[\begin{matrix}x \\ y \\z\end{matrix}\right] = \left[\begin{matrix}5 \\ 1 \\ 8\end{matrix}\right]\]

Answer 2

not sure which parts needs explanations so please ask :)

Answer 3

Thank you for showing me the matrix. I needed to find out the matrix dimension that was formed from that system of equations, and now I am able to answer that question. Thank you so veeeerrry much! =)
