# Text in aligned-environment

Is it possible, that the text starts at the second line of the equation?

\documentclass[a4paper,10pt]{article}
\usepackage{amsmath}

\begin{document}
\begin{itemize}
\item First thing:
\begin{aligned}[t] c^2&=a^2+b^2\\ d^2&=e^2+f^2 \end{aligned},
where $a,b$ and $c$ are supposed to be real numbers and $d,e$ and $f$ complex numbers, respectively.
\end{itemize}
\end{document}

• anything is possible but it would look pretty weird, I would put the where... under the alignment Mar 3, 2018 at 15:58
• Ok, how would I do that? And anyway, how would I achieve my first idea? Then I can decide what's better :)

• Replace t by b. Mar 3, 2018 at 16:04
• No, that's not good, then the First thing is also moved to the bottom.

• So, by text you mean where...? Mar 3, 2018 at 16:13

I would do 3 or 4

\documentclass[a4paper,10pt]{article}
\usepackage{amsmath}

\begin{document}
\begin{enumerate}
\item First thing:
\begin{aligned}[t] c^2&=a^2+b^2\\ d^2&=e^2+f^2 \end{aligned},
where $a,b$ and $c$ are supposed to be real numbers and $d,e$ and $f$ complex numbers, respectively.
\item First thing:
\begin{align*}
c^2&=a^2+b^2\\
d^2&=e^2+f^2
\end{align*}
where $a,b$ and $c$ are supposed to be real numbers and $d,e$ and $f$ complex numbers, respectively.
\item First thing:\vspace{-5pt}
\begin{align*}
c^2&=a^2+b^2\\
d^2&=e^2+f^2
\end{align*}
where $a,b$ and $c$ are supposed to be real numbers and $d,e$ and $f$ complex numbers, respectively.
\item First thing:
\begin{aligned}[t] c^2&=a^2+b^2\\ d^2&=e^2+f^2 \end{aligned},

where $a,b$ and $c$ are supposed to be real numbers and $d,e$ and $f$ complex numbers, respectively.

\item \mbox{}\\[-10pt]\raisebox{17pt}{First thing:}
\begin{aligned}[b] c^2&=a^2+b^2\\ d^2&=e^2+f^2 \end{aligned},
where $a,b$ and $c$ are supposed to be real numbers and $d,e$ and $f$ complex numbers, respectively.
\end{enumerate}

\end{document}

• not every document class fails to indent a new paragraph in a list. Mar 3, 2018 at 21:32
• @barbarabeeton true but one thing at a time:-) (might be a rare case that \\  is better than a blank line, I agree. Mar 3, 2018 at 21:38
• no; if you're using aligned (which is sensible), \\  doesn't yield the same vertical spacing. it would be \noindent. Mar 3, 2018 at 22:12
