# Is there any other way of typing aligned equations aside from cases and align?

I want to type aligned equations

x = a
y = b
z = c


I only know two ways of achieving this. One is using \begin{align}, the other is by using \begin{cases} wrapped within a \begin{equations}.

Is there any other way to achieve aligned equations?

• align is the most used one. Your second approach sounds ugly. Commented Nov 24, 2018 at 21:05
• It mostly depends on what you're trying to achieve. Commented Nov 24, 2018 at 21:07
• You also have alignat, which lets you control the spacing between alignment columns , and flalign. Commented Nov 24, 2018 at 21:31
• the amsmath package offers align, flalign, alignat, as top level environemnts, or inside equation aligned or alignedat depending if you want one equation number or 3. Don't use cases for such a display. Commented Nov 24, 2018 at 21:59

\documentclass{article}

\usepackage{amsmath}

\begin{document}

align
\begin{align}
x &= a \\
y &= b \\
z &= c
\end{align}

alignat
\begin{alignat}{1}
x &= a \\
y &= b \\
z &= c
\end{alignat}

flalign
\begin{flalign}
x &= a \\
y &= b \\
z &= c
\end{flalign}

equation/aligned
\begin{aligned} x &= a \\ y &= b \\ z &= c \end{aligned}

equation/alignedat
\begin{alignedat}{1} x &= a \\ y &= b \\ z &= c \end{alignedat}

equation/cases
$$f(x)=\begin{cases} -1 &x = a \\ 0 &y = b \\ 1 &z = c \end{cases}$$

\end{document}
