    Is that 6/14=7/(x-3) or 6/14=(7/x)-3?

    Note the format the Jameson used:
    6/14 = 7/(x - 3)

    First reduce the fraction on the LHS:
    3/7 = 7/(x - 3)

    Multiply both sides of the equation by 7(x - 3):
    7(x - 3)*(3/7) = 7(x - 3)*[7/(x - 3)]

    3(x - 3) = 7*7

    3x - 9 = 49

    3x = 58

    x = 16

    Since x is not equal to 3 (this is prohibited by the original expression) this solution is valid.
