To get n by itslef, you have to divide -9 by both sides of the equation, however, since the -9 is in-between the two lines on the outside of it, it is therefore an absolute number. Usually when you divide both sides of an equation like this by a negative number, you would flip the less than symbol (>), but since the -9 is an absolute number, the negative does not count for anything. When you divide 63 by 9, you do not have to flip the less than symbol.
