Hello, I'm trying to typeset some linear algebra exercises for my students; the exercises will be within a table, and each second element will be a system of linear equations. This sort of thing: \starttable[|l|M|l|M|] \NC (a) \NC % \startmathalignment[n=7,align={right,middle,right,middle,right,middle,right}] \NC 3x\NC +\NC 6y\NC -\NC 2z\NC =\NC -13\NR \NC -6x\NC -\NC 9y\NC +\NC 5z\NC =\NC 22\NR \NC 3x\NC +\NC 3y\NC -\NC 5z\NC =\NC -13\NR \stopmathalignment \NC (b) \NC % \startmathalignment[n=7,align={right,middle,right,middle,right,middle,right}] \NC x\NC +\NC 3y\NC +\NC 3z\NC =\NC -4\NR \NC x\NC +\NC 4y\NC +\NC 5z\NC =\NC -5\NR \NC 2x\NC +\NC 4y\NC +\NC 3z\NC =\NC -5\NR \stopmathalignment \NC\AR \stoptable But this doesn't work. There seems to be a problem with the mathalignment environment within the table. What do I need enclose these in so that they will be treated as displayed equations within the table environment? I'm using MkII. Thanks, Alasdair -- Blog: http://amca01.wordpress.com Web: http://bit.ly/Alasdair Facebook: http://www.facebook.com/alasdair.mcandrew
