    Well think of the question with the less than or equal to symbol as an equal sign. Just remember if you divide by a negative the symbol will become a greator than or equal to.

    One treats an inequality just like and equation algebraically except that the inequality is reversed when multiplied or divided by a negative number.

    Well I think you forgot 1 step that both I and wetlife have said about multiplying or dividing by negatives.

    DLS the problem with your work is that your less than or equal to sign cannot end up as a greator than sign. It is impossible for that to happen.

    yes ashylnn, but you are missing the last step. You must simplify equation. .You are not looking for what negative b is, but you are looking for just the variable b

    yes so i would divide it like this ?? |dw:1357805403002:dw|

    ummm.. no. Because you want b on one side, you would not divide both sides by b. Hint: -5= -1*5.

    b/b=1 if b not 0 and 6/b=6/b.

    ashylnn my point is to help. It is not to give answers. The example of -5 = 5*-1 is an example to help give you a hint. It has nothing to do with your problem. It is to give you an idea of where you need to fix

    Correct. I am assuming that you either multiplied both sides by -1 or divided both sides by -1

    multiplying by both sides is the correct way. I am also saying that if you had divided it by -1 you would have gotten the same answer. Both ways are correct

    Also I have noticed you are using the asteric symbol. Just remember that asteric symbol is only used on the computer. When done on paper, the correct way is to use a dot in the middle|dw:1357806252885:dw|
