Latex for-and in equation

Question

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.

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

I request for help to correct the code. Thank you

Answer 1

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}

Answer 2

Numbered...

\documentclass{article}
\usepackage{amsmath,amssymb}
\begin{document}
\begin{equation}  
\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{equation}
\end{document}

Answer 3

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{equation}
\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}
\end{equation}
\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.

Answer 4

   \begin{document}
    \begin{tabular}{p{1cm}l}    
    $P_d(\delta_L) =$ & $ P_p(\delta_S,L_S)$\\
          &\text{for $\delta_S>\delta_{0S}$ and 
      $\delta_L<\delta_{0L}$}
   \end{tabular}
   \end{document}

How about testing this? Simpler and has more freedom.
