    Works, exactly what I asked. However there is another question

    I want some particular multline to be arranged like

    aaaaaaaaaaaaaaaaaaaaaaaaaaaa
                                       bbbbbbbbbbbbbbbbbbbb
                                       cccccccccccc

    So some combi of multline and align. What is the best way to achieve this?

for the last two lines, use the "subsidiary"
environment aligned:

  \begin{multline}
    aaaaaaaaaaaaaaaaaaaaaaaaaaaa\\
    \begin{aligned}
      bbbbbbbbbbbbbbbbbbbb\\
      cccccccccccc
    \end{aligned}
  \end{multline}

this and some other "alignment building blocks"
are described in the amsmath user's guide,
amsldoc.* ; you can get a pdf file either from
ctan or from a link on
  http://www.ams.org/tex/amslatex.html
if it's not already on your system.
