Understanding the Difference between Expressions and Equations

This lesson explains the difference between expressions and equations by examining their characteristics. Expressions represent values and can include variables, constants, and operations but do not have solutions. Equations, on the other hand, equate two expressions and can have zero, one, or more solutions. The video provides examples of both expressions and equations, demonstrating how to simplify expressions and solve equations. It also covers the graphical representation of equations with infinitely many solutions.
