In this lesson on solving linear inequalities, the video math tutor provides a self-tutorial on how to solve typical linear inequalities, including double inequalities and compound linear inequalities, using methods such as number line graphs and interval notation. The properties of inequalities are also reviewed, and answers are presented in inequality notation, interval notation, and set notation. Additionally, the lesson covers how to translate English phrases into inequalities and solve word problems.

The tutor goes over how to draw number line graphs. Also covered is the Double Inequality (a < x < b). Properties of Inequalities are reviewed. Answers are presented in Inequality Notation, Interval Notation, and Set Notation. Compound Linear Inequalities are solved and graphed. Finally, English Phrases are translated into inequalities and some Word Problems are solved.
