Int Algebra: Systems of Linear Equations 205

This lesson is part of the series: Intermediate Algebra, Pre Calculus

This 86 minute intermediate algebra lesson focuses on solving linear (first degree) equations. The equations in a system of two linear equations are studied together with both graphic and algebraic methods used for solution. This lesson will help you understand how to solve:
- using the graphing method
- algebraically using the substitution method, the the comparison method, and the addition or subtraction (elimination) method (e.g. solve for x and y in using 5x + 3y = -14 and 3x – 6y = -11)
- a consistent and dependent system of two linear equations algebraically
- a consistent and independent system of two linear equations
- an inconsistent system of two linear equations
- a system of linear equations in three variables

This lesson contains explanations of the concepts and 19 example questions with step by step solutions plus 6 interactive review questions with solutions.

Lesson that will help you with the fundamentals of this lesson:
- 190 Coordinate Plane, Distance & Midpoint Formulas, Slope (http://www.mindbites.com/lesson/5075)

All lessons have been prepared by a certified teacher, B.A., B. Ed. (Math Major) with 30+ years experience teaching Math to High School Students and Continuing Education learners. She has a reputation for teaching the math class that “you want to be in.” For more information please visit Math Made Simple: http://www.mathmadesimple.com/

Through her teaching and tutoring experiences, the growth of technology and the internet she recognized a need to make comprehensive math lessons available via the Internet to help:

- High school students who have missed a class or maybe just need a little extra help or are in sports or other extra curricula activities
- Teachers looking for a way...

Good lesson

This lesson was easy to follow. With my continuing troubles with the instructors voice aside, there were tons of examples that were easy to follow along with. After the first few I was pausing the video, working the problem, then checking as she explained it which was a good way to catch a few of the mistakes I was doing.
