Inequality
For example, start with a true statement -6y<-12. When both sides are divided by -6, the result will become y<2. In this statement, the symbol need to be reversed in order to have a true statement, which produces y>2 as the correct answer. In the number line (see figure Inequality 2), a closed shaded circle points out that it is included in the solution set. An open circle points out that it is not included in the solution set.
