    Cannot determine from the info given. There needs to be more information. Think about it, there's no way to determine the number of tickets sold at the door vs. pre sold

    Let d denote the number of tickets sold at the door, and p the number of pre-sold tix. Then the problem furnishes you with two linear equations:

    d + p = 410
    6d + 4p = 2,000

    Solve for d and p either by substitution or by elimination.

    Yup, that's the way to do it.

    Of course, any other variable used is acceptable :)
