Linear optimization

Hello everybody, I need to optimize a linear system involving typically six equality constraints for eight variables, and a minimum level for each of the variables. I tried to do this using LinearProgramming but there seems to be no way to specify that some of the constraints are to be equality (in MMA 2.2.2 for the Mac, Student version). So I was looking for some other way, possibly using the Simplex algo- rithm. There is a notebook called "simplex.ma" in MathSource but it just draws the table, without doing an iteration. Does any of you out there know where to get a good implementation from (or how else to solve that problem)? Thanks a lot for any hints!
