Finite Mathematics & Applied Calculus: Review Exercises: Systems of Linear Equations

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.

Learners must think critically about the graphical and algebraic forms of a system of linear equations in order to come up with their own system when given a point that is the solution to the system.

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...

Systematically check a solution in a system. Given a point and a system, the presenter checks to see if the point is a solution to the system. Pupils understand what it means to be a solution to a system. The video shows both...

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...

Systematically take an algebraic approach. Learners view an informative video that works four examples of solving a system of equations using substitution. The presenter works through the process of finding the solutions for each system....

The topic summary outlines systems of linear equations and matrices. Some topics reviewed are linear equations in two unknowns, augmented matrix, and Gauss Jordan row reduction. The resource consists of definitions, notes, and examples.

Let the learners take the driving wheel! The class solves systems of linear equations and applies the concepts of systems to solve a real-world situation about parking cars and buses. They then use calculators to create a visual of their...
