Linear Equations: Math Videos

This series covers linear equations and how to use them. You will learn the forms of a line's equation, solve systems of equations by elimination and substitution, and tackle word problems about age, percents, and averages. You will also learn direct and inverse variation. These are core skills for the GED and for real-life problem solving. You should be comfortable with basic arithmetic and simple equations.
