    Basically, you have to divide by - 1 on both sides and when ever you divide any side of the inequality by a negative number, you would have to switch the signs.

    So:

    9>-r

    9/-1 > - r/-1

    -9
    or

    r>-9

    I never learned the rules of when you must change the direction

    of the inequality. But you can solve this one without even knowing

    that rule:

    You said 9 > - r

    Add 'r' to each side: r + 9 > 0

    Subtract 9 from each side: r > - 9
