I would like to get a nonstandard alignment in the following code:
\begin{align}
\text{First left hand side} & = \text{First right hand side} \\
\text{Second left hand side} & = \text{Second right hand side} \\
& = \text{Loooooooooooooooooooooooooooooooong expanded right hand side}
\end{align}
where the last line should not be aligned with the first two lines. I know that I could split the last line to form multiple right hand sides, but I would rather avoid it, as it would fill four equations in my case.
I found an evil way of doing it by nesting align and gather:
\begin{gather}
\begin{align}
\text{First left hand side} & = \text{First right hand side} \\ %% \label{} does not work here
\text{Second left hand side} & = \text{Second right hand side}
\end{align}\\
= \text{Loooooooooooooooooooooooooooooooong expanded right hand side} \label{eq3}
\end{gather}
but alas, while this gives the visual output I want, I can not use labels to refer to the equations within the align.
I also don't want to place &
somewhere in the middle of the third line due to spacing issues, and because it is a fragile way of doing that.
So how can I type that
- the first and second line align at
=
- the third line is not aligned ot the first two lines (preferably flushed right)
- all three lines are numbered, and can be referenced
- all three lines are in one equation group (for the semantics and the spacing)?
&
the last line becomes a left hand side, pushing everything right. The last line shall be really that long so it needs both the space of the left and right hand sides of the first two lines. – mafp Nov 26 '12 at 17:27
