  1. If you want to avoid fractions, you might want to look at my solution to your question when you first posted it
    http://www.jiskha.com/display.cgi?id=1328440122

    You could take my equation

    9x - 8y = 110
    8y = 9x - 110
    divide by 8
    y = (9/8)x - 110/8
    y = (9/8)x - 55/4

    and end up with the same equation that Declan had at the end

    I much prefer my method to working with all those factions.
