You have 20 pigs and 5 days in which to kill them. But you can only kill an odd number of pigs in a day, you must kill at least 1 pig a day!

For example, I need to write an equation to a line that is perpendicular to 2x + 3y = 6.

I don't need the exact answer, as much as I need a complete and hopefully simple explanation as to how to carry out this problem. I really appreciate your help!!!
