Theses, Books, Title pages ⇒ how to center align environment?

[templateuser]

Hi,

I'm trying to center a couple of equations but they're stick to the left side. I want to center:

Code: Select all

\begin{align*}
y = ad + da\\
y = ad + da
\end{align*}

When I work with tables I can solve the problem (as in basic templates) using

Code: Select all

\begin{center}
...
\end{center} 

but I don't find the way with eqnarray or align environment in this template. Can you give me a hand? thanks!

hi,
If I delete the option fleq in the options of document class I resolve my problem.
This now can be closed.
