    Since this is a “Matrix Algebra” course, we need to learn how to do ‘matrices’ in LaTeX. Double click on the following cell to see the LaTeX code to build a matrix:

    Basic matrix notation:

    \[\begin{split}
    \left[
    \begin{matrix}
    1 & 0 & 4 \\
    0 & 2 & -2 \\
    0 & 1 & 2
    \end{matrix}
    \right]
    \end{split} \nonumber \]

    Augmented matrix notation:

    \[\begin{split}
    \left[
    \begin{matrix}
    1 & 0 & 4 \\
    0 & 2 & -2 \\
    0 & 1 & 2
    \end{matrix}
    \, \middle\vert \,
    \begin{matrix}
    -10 \\ 3 \\ 1
    \end{matrix}
    \right]
    \end{split} \nonumber \]

    Do This

    Using LaTeX, create an augmented matrix for the following system of equations:

    \[4x + 2y -7z = 3 \nonumber \]

    \[12x + z = 10 \nonumber \]

    \[-3x -y + 2z = 30 \nonumber \]

    Question

    In LaTeX, what special characters is used to separate elements inside a row?
