Systems of equations

A handy package for easily typesetting systems of equations is systeme. Load the package with the following commands:

\usepackage{systeme} % For easily aligning systems of equations
    \sysdelim.. % To get rid of the left brace that is there by default

Here is an example illustrating the basic syntax:

    Find all solutions to the following linear system:
    \[
        \systeme{x-y+z=0, y+2z=-2, x+y-z=2}.
    \]

This will produce the following:

Note that this won't work in Obsidian (without doing some sneaky stuff to load additional LaTeX packages, which I haven't yet investigated).
