# Latex for-and in equation

I need to write equation as shown in the attached image in LaTex. So far, I have written it like shown below but I can't figure out how to separate (or write properly) the "for" and "and" part of the equation similar to that shown in the image.

$$P_d(\delta_L)=P_p(\delta_S,L_S) for \delta_S>\delta_{0S} and \delta_L<\delta_{0L}$$


I request for help to correct the code. Thank you

• I tend to use \qquad\text{for $\delta_S>\delta_{0S}$ and $\delta_L<\delta_{0L}$}, this way the math and condition has proper semantic markup – daleif Mar 25 at 17:15

You can use align*.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align*}
P_d(\delta_L) &= P_p(\delta_S,L_S)\\
&\phantom{{}={}}\text{for $\delta_S>\delta_{0S}$ and $\delta_L<\delta_{0L}$}
\end{align*}
\end{document}


Numbered...

\documentclass{article}
\usepackage{amsmath,amssymb}
\begin{document}
\begin{aligned}[b] P_d(\delta_L)={}&P_p(\delta_S,L_S)\\ & \text{for } \delta_S>\delta_{0S} \text{ and } \delta_L<\delta_{0L} \end{aligned}
\end{document}


Your picture hints you're using a two-column format. Here's my proposal with multlined:

\documentclass[twocolumn]{article}
\usepackage{amsmath,mathtools}
\usepackage{newtxtext,newtxmath}

\usepackage{lipsum} % for context

\begin{document}

\lipsum*[3]
$$\begin{multlined}[b][0.66\displaywidth] P_d(\delta_L)=P_p(\delta_S,L_S) \\ \text{for \delta_S>\delta_{0S} and \delta_L<\delta_{0L}} \end{multlined}$$
\lipsum[4]

\end{document}


The lipsum package is just to provide context. The newtx... packages are to get Times-like fonts as in your picture.
