Hi Xan,
I think Wolfgang meant that one should something like the following
construction:
% define here a new math-aligned structure:
\definemathmatrix[alignedcases]
[align={right,left,left},
distance=3pt,
left={\left\{},
right={\right.},
style=\displaystyle]
\starttext
\startformula
\startalignedcases
\NC x - 2y + 2z \NC = 1 \NR
\NC 2 x + y - z \NC = 2 \NR
\NC 4 x - 3y + 6z \NC = 7 \NR
\stopalignedcases
\stopformula
\stoptext
Best regards: OK
