I would like to use an align environment with a single equation number but with multiple equations per line. For example, the following two pieces of code work:

begin{align}
a&= 1 & b&= 2 + 3\\
c&= 4 + 5 & d&= 6\
\end{align}

begin{align}\begin{split}
a&= 1\\
c&= 4 + 5
\end{split}\end{align}

The second example succeeds in having one equation reference in the middle, and the first succeeds in having multiple equations per line. How might I have multiple equations per line with one equation reference? Thanks!

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. Anyways, it seems that this solves the problem: tex.stackexchange.com/q/13396 Please confirm whether it solves your problem or not. – yo' Nov 12 '14 at 15:21

\begin{equation}
\begin{aligned}
  a &= 1
&
  b &= 2 + 3
\\
  c &= 4 + 5
&
  d &= 6
\end{aligned}
\end{equation}
