# Align multiple lines in 'multline' command

\begin{multline}
e^{-\lambda T} = ( 1 - \log S_j^* (T))^{\frac{1}{1-\theta}} \\
- \lambda T = \dfrac{1}{1-\theta} \log ( 1 - \log S_j^*(t))  \\
T = \dfrac{1}{\lambda (\theta-1)} \log ( 1 - \log S_j^*(t))
\end{multline} I have three lines of equations which appears like the attached image file. I would like to center them or align to the left. How can I do that?

• use gather rather than multline ? (multline is intended for one long equation, which is why it starts on the left and finishes on the right) – David Carlisle Nov 23 '14 at 22:00

Use align, or if you want only one number use aligned inside an equation.

\documentclass{article}
\usepackage{mathtools}
\begin{document}
\begin{align}
e^{-\lambda T} &= ( 1 - \log S_j^* (T))^{\frac{1}{1-\theta}} \\
- \lambda T &= \dfrac{1}{1-\theta} \log ( 1 - \log S_j^*(t))  \\
T &= \dfrac{1}{\lambda (\theta-1)} \log ( 1 - \log S_j^*(t))
\end{align}

\begin{equation}
\begin{aligned}
e^{-\lambda T} &= ( 1 - \log S_j^* (T))^{\frac{1}{1-\theta}} \\
- \lambda T &= \dfrac{1}{1-\theta} \log ( 1 - \log S_j^*(t))  \\
T &= \dfrac{1}{\lambda (\theta-1)} \log ( 1 - \log S_j^*(t))
\end{aligned}
\end{equation}
