    if 9 times a number is decreased by 6, the result is 111

    A number means an arbitrary variable, let's call it x.

    9 times a number:
    9x

    Decreased by 6
    9x - 6

    The result is 11, this means we set 9x - 6 equal to 11
    9x - 6 = 11

    To solve this equation for x, use our equation calculator
