Linear Expressions: Math Videos

This series focuses on systems of equations and inequalities. You will learn how to solve systems by elimination and substitution, how to tell when a system has one, none, or infinitely many solutions, and how to solve systems with three variables. Fun examples include a king's cupcakes and a talking bird. Systems help solve real problems with more than one unknown. You should be comfortable with basic linear equations.
