With dynamic animation, this six-part series explores several techniques for solving linear systems. The series begins with the method of solving one linear equation with one variable. This is accomplished when the value of the variable that will make the statement true is found. The solving of one linear equation with two variables leads to the concept of a "relation," which is then graphed on a Cartesian plane. Methods for solving linear systems involving two equations with two variables are also demonstrated. They include graphing, substitution, comparison, and elimination techniques using addition and subtraction. In the final program, concepts relating to linear systems with three equations in three variables are explored. 6-part series, 10 minutes each.
