Solving Systems of Linear Equations

Lesson:	205 - 1 Hour 25 Minutes
Summary:	The focus of this lesson is the solving of systems of linear (first degree) equations. The equations in a system are studied together and the methods, both graphically & algebraically are explored. After this lesson, you will be able to: - identify the three types of systems of linear equations - solve systems of two linear equations graphically - solve systems of two linear equations algebraically using: a) the substitution method b) the comparison method c) the addition or subtraction method -solve systems of three linear equations algebraically
