this is a disjunction problem using "or". When you solve the first one, you have to flip the sign to less than because you are dividing by a negative number. Doing this gives you x<-7. The other one is "normal", and dividing gives you b>-1. Graphing that on a number line is an open circle at -7 and includes all the values to the left of -7, and graphing the other one on the same number line is an open circle at -1 and includes all the values to the right of -1. The word "or" is used because they do not share any solutions.
