Question 525872: Hi! My teacher told me that you change the sign for the inequality only if the negative number is on the left side (with the variable) when you are dividing or multiplying, is that true? Then if you have a question like -3x>9 then the sign will be changed but if you have 3x>-9 then the sign will not be changed because the negative number is on the right. Please answer this question, I really don't get it, and on a test I didn't change the sign if the negative number was on the right. Please answer as soon as possible, I'm really scared and worried right now! Thank you for answering! :)
