I'm trying to convert this linear equation: -(4+4x+y) / 17^(1/2) = (2+x+y) / 2^(1/2) into the form: (a_)*x + (b_)*y + (c_) = 0 This sounds simple enough, but I can't figure out how to make Mathematica do it. My TI-89 does it automatically, but I need to be able to do this like a batch process for a bunch of linear equations. Heres the solution the TI-89 gives me: \!\(\* StyleBox[\(\((\(\(-4\)\ \@17\)\/17 - \@2\/2)\)\ x + \((\(-\@17\)\/17 - \ \@2\/2)\)\ y - \(3\ \@17\)\/17 - \@2 = 0\), FontWeight->"Bold"]\) Just copy and paste that mess into Mathematica and it will change into the equation at the top, but in the form that I want it. I haven't been using Mathematica for long. I'm used to my TI-89; I've been using it for years.
