You cannot condense TWO distinct linear constraints into ONE linear constraint, where the distinction is based on another linear computation. You certainly cannot convert an inequality into an equality constraint, based on the values of another constraint.

Even worse, testing for exact equality among floating point numbers will cause problems, because your very next question will be an anguished one, wondering why your code does not work.
