Math & Science ⇒ amsmath | Correct Alignment for multi-line Equations

[marcdein]

I have an equation like the following

Code: Select all

\begin{align}
A &= B + C \\
  & + D
  &= E + F + G
\end{align}

In my text, B, C, D are actually some pretty long expressions, which is why I have to go over to the next line. My question: how can I align the second line so that the "+" in "+ D" is actually aligned with B rather than with the equal sign of the previous line?

Of course, I still want the equal sign in the third line to be aligned with the one in the first line.

I figured out how to do it using the {split} environment together with the new command:

Code: Select all

\newcommand{\newln}{\\&\quad{}}

Thanks for posting your solution!

It works also with align:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
A &= B + C \\
  &\quad + D \\
  &= E + F + G
\end{align}
\end{document}
