Best ResponseYou've already chosen the best response.0so you need to get x by itself, to do that you have to divide everything by 2. dw:1361036855393:dw Then what would you get?

Best ResponseYou've already chosen the best response.0so if you dived that out you should get the right answer(: the inequality signs don't change because you aren't multiplying or dividing by a negative number.
