Khan Academy: Lesson: Solving Systems of Linear Equations Harder Example

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.

In this systems of equations worksheet, students use the substitution method to solve systems of linear equations. This one-page worksheet contains eight problems, with answers.

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...

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...

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. 

Picture the solution. The Mathispower4u Algebra I video uses three examples of finding the solution of a system of linear equations given as a graph. Pupils use their knowledge of linear graphs to also identify the equations for the...
