Hi!
No, you have not gone wrong, but syntax has changed a bit. This works now:
\starttext
\placeformula
\startformula
\startmathalignment[n=7,align={1:right,2:left,3:right,4:left,5:right,6:left,7:right}]
\NC x_1 \NC + \NC x_2 \NC + \NC 6x_3 \NC = \NC 170, \NR
\NC 3x_1 \NC - \NC 110x_2 \NC - \NC x_3 \NC = \NC 4, \NR
\NC 14x_1 \NC + \NC 13x_2 \NC + \NC 10x_3 \NC = \NC 25. \NR
\stopmathalignment
\stopformula
\stoptext
This was done while changing alignments in matrices (and thus also in
alignments, it seems). You can now do align=all:right for example to
get all columns in a matrix right-aligned.
Hans: since people like to use right/left/right/left/ when typesetting
systems of equations... maybe one could add odd:right and even:left as
well?
