Inequalities and Basic Equations

The video tutorial covers Module 4 Lesson 24, focusing on applying substitution to solve equations and inequalities. It begins with an introduction to equations and inequalities, followed by exercises to determine the truth of number sentences. The lesson then explores using substitution to solve equations and experimenting with inequalities. The tutorial concludes with final exercises and a summary of the lesson.
