Hallo,
i will create two equations like:
x^2+y^2=z^2+3
x^2+y^2+z^2=3*y

I did it with ALT+& and can write the two equations like in Latex. But how 
can 
i align to the equal sign? Like this one in Latex

\begin{equation}
x^2+y^2 &= z^2+3
x^2+y^2+z^2 &= 3*y
\end{equation}

or &=& instead.
Is it not possible in texmacs?

Thx
Marten
