How to indent equations?
Try something like
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation}
\begin{split}
A ={} & B + C + D + E + F + \\
& G + H + I + \dots, \quad\text{while $x$ is true}.
\end{split}
\end{equation}
\end{document}
Output
If you don't want the equation to be numbered use equation*
instead of equation
.
As Svend suggested in the comment, in this case it is probably better using \dotsb
instead of \dots
.
You can use the align
environment if you want. Remove the *
to get the numbered equation form. The following is MWE:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align*}
A {}={} & B + C + D + E + F +\\
& G + H + I + \dotsb, \quad \text{while $x$ is true.}
\end{align*}
\end{document}
Another flavor would be like:
\[
\begin{aligned}
A {}={} & B + C + D + E + F +\\
& G + H + I + \dotsb, \quad \text{while $x$ is true.}
\end{aligned}
\]
or
\[
\begin{array}{r@{}c@{}l}
A &{}={}& B + C + D + E + F +\\
& & G + H + I + \dotsb, \quad \text{while $x$ is true.}
\end{array}
\]
This does not give any numbered version but keeps the alignment. I recommend you read the amsmath
documentation and other math related sources to get acquainted with alignments in equations. For example, here in TeX.SX you can make a quick search and you will see several examples of alignment. For instance if I search alignment in equations
I would get lots of examples. (click me)
