# [NTG-context] multi-line equations with \left( and \right.

Hi,

I try to do that

\startformula
\startalign[left={\left(\,},right={\,\right.}]
\NC x - 2y + 2z \NC = 1 \NR
\NC 2 x + y - z \NC = 2 \NR
\NC 4 x - 3y + 6z \NC = 7 \NR
\stopalign
\stopformula

but it does not work.
Can anyone help me?

Thanks,
Xan
