System of Two Equations with a Quadratic Equation

Introduce the inverse matrix method to solve systems of linear equations both algebraically and graphically. Using given data, your class checks their answers with graphing calculators. Handouts are included in this well-thought out lesson.

One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

Determine a solution through accurate graphs. Using 2 examples, the narrator walks viewers through the steps to graph a system of linear equations to find the solution. 

Not all systems have a single solution. To begin the video, the narrator reviews the different number of solutions possible with a system of linear equations. He continues with examples of solving systems of equations by graphing. Unlike...

Elimination is another method for solving systems of equations, in addition to graphing and substitution. Sal's lecture is straightforward to understand, even for students who struggle with learning. By having a variety of options when...

Twenty problems present a variety of practice graphing and solving systems of linear inequalities. They are given with each step to the solution cleverly revealed one at a time. You can work each step of the problem then click the "View...
