Math & Science ⇒ Alignment in a multi-line Equation

[erictamlam]

Hi all,

I want to type an equation as attached in the image, but not sure which equation environment can achieve the exact outcome, split, align, {eqnarray}, {array}?

Anyone knows? Thanks in advance.

I would use an align environment if both equations should be numbered, align* if there should not be a number, split within an {equation} environment if both lines should get one number together.

For the expression with the brace, you could use cases.

Here is a MWE based on Stefan's suggestions.

Code: Select all

\documentclass{article}

\usepackage{amsmath}

\begin{document}

\begin{align}
A &= B\\
  &=
\begin{cases}
      C,  & \text{D},\\
\text{E}, & \text{F}.
\end{cases}
\end{align}

\end{document}
