    Gauss-Jordan Elimination Method w/Matrices

    HI All,
    I need help solving this Gauss-jordan elimation word problem:
    I need to define the variables; if necessary or applicable, organize the information given into a chart, and setup a system of equations. Then solve using Gauss-Jordan method.

    A minor league baseball park has 7000 seats. Box seats cost$6,grandstand seats cost $4,and bleacher seats cost $2. When all seats are sold, the total revenue is $26,400. If the number of box seats is one-third the number of bleacher seats,how many seats of each type are there?

    Thanks for your help

    Introduce variables

    x - the number of box seats
    y - the number of grandstand seats
    z - the number of bleacher seats

    Use these variables and what you are told to formulate three equations.

    The solve using the method you have been shown.
