Hi all,
I'd like to typeset a system of simultaneous equations. I want it to have a brace on the left (like "cases"), but inside I want it to have two columns aligned like "align". Also, I'd like to have the vertical space between the equations be small (like in cases), not so big as in align.
How to do this?
I do not completely understand what you want. Do the following give the desired output. \starttext \startformula \startcases[align={right,left},distance=3pt] \NC 2x + 3y \MC{} = 10 \NR \NC 3x + 2y \MC{} = 5 \NR \stopcases \stopformula \startformula \startmatrix[align={right,left},distance=3pt,left={\left\{}, right={\right.}] \NC 2x + 3y \NC{} = 10 \NR \NC 3x + 2y \NC{} = 5 \NR \stopmatrix \stopformula \stoptext The {} after the alignment \NC is useful if the next symbol is something that can be a uniary or binary symbol (eg, + or -). The {} tells tex to treat is as a binary symbol. If you frequently need something like this, you can use definemathcases/definemathmatrix to define a new environment with appropriate parameters.
