[Tex/LaTex] Multiple alignments

alignhorizontal alignment

If I have a string of equations whose equal signs are aligned and one of the equations is too long and needs to span multiple lines, how do I create a second alignment. For instance, in the following example

      &           +eqn2_part3\\  

How do I align the equals signs and the plus signs.

Using boxes via \phantom is also an option, if alignment characters like && get in the way for long equations:

\usepackage{amsmath}% http://ctan.org/pkg/amsmath

A correction for the spacing around binary operators ({}+) and relations ({}=) is required though. See Herbert's mathmode document for more on AMS environments and alignment.
