Question 641323: My question is not about solving homework. Next week is midterms and I have a HORRIBLE grade in pre-algebra. We are having a final test over reciprocals. I need a LOT of help. So basically what you do is you swap the number over. So if the division problem is 1/3 divided by 1/2 you would be solving for: 1/3 x 2/1 right? and the answer would be 2/3. Am I correct? Thank you so much for reading.

Question 653130: It's been several decades since I've done this so I appreciate the help.
-5x/3 + 2 > 12 = x < -6
Unfortunately I get x > -6
So my question is when using "< or >" and negative numbers, do you reverse the "<, >" when bringing the negative to the other side of the equation?
