I am currently trying to label an line in an align* environment using \tag; however, the tag appears on the left side of the line instead of on the right. How do I move this label to the right side?

Thank you!

 %latex
\documentclass{amsart}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{pgfplots}

\begin{document}
\begin{proof}
    We begin by formulating the profit maximization problem and taking the first order condition.
    \begin{align*}
        \max_q \left(pq-C(q)\right) \\
        \max_q \left(pq-10q-q^2 \right) \\
        \frac{\partial \pi}{\partial q}=p-10-2q=0 \tag{First-Order Condition}
    \end{align*}
    We then formulate market balance by substituting $nq$ in for $Q$.
    \begin{align*}
        p=100-6Q \\
        p=100-6nq \tag{Market Balance}
    \end{align*}
    Lastly, we write the expression for profits for a firm and set this equal to zero.
    \begin{align*}
        pq-C(q)=0 \\
        (100-6nq)q-10q-q^2=0 \tag{Equilibrium Entry}
    \end{align*}
\end{proof}
\end document

Tag on left

  • Do you want this only for these \tags, or for all equation numbers? If the latter, add reqno to the class options, see Placing equation numbers on the right – Torbjørn T. Oct 31 '15 at 18:31
  • Off-topic, but maybe still of relevance: None of the three align environments in your example contain a single alignment point; as a result, the three equation groups are all right-aligned. Is this deliberate? – Mico Oct 31 '15 at 18:36
  • I was intending to align them on the equals signs. Sorry about that. I do not want equation numbers, however, I want to give them text names. – cpage Oct 31 '15 at 18:52
  • No, my point was that if you have numbered equations somewhere else in your document, then reqno will move their numbers to the right as well. Is that what you want, or do you want just these three \tags moved to the right? – Torbjørn T. Oct 31 '15 at 19:24
  • I do not have numbered equations elsewhere. reqno worked perfectly. Thank you. – cpage Oct 31 '15 at 22:11
