Lesson: 24: Equations, Inequalities and Line Graphs
Topic: Inequalities on the Number Line
Domain: Algebra

An inequality is solved with the same moves as an equation, with one exception: multiplying or dividing by a negative flips the sign round.

Study Tip

3 < 5 is true, but multiplying both sides by −1 gives −3 > −5, because a negative reverses the order of the whole number line.
