Model a Real-Life Situation Using a System 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.

Frugal shoppers, linear systems are your friends! Armed with information about the rates different pizza places charge for their pizzas and deliveries, learners write equations to represent each restaurant. After analyzing the graphs,...

Here is a instructional activity that really delivers! Middle schoolers collaborate to consider pizza prices from four different pizza parlors. Using systems of simultaneous equations, they graph each scenario to determine the best...

Middle and high schoolers solve systems of equations relating to money and explore substitution and elimination strategies. In this activity, pupils review The Chicken and Pigs problem and compare their solutions with the graphing...

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...

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...

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. 

Linear equations, coordinate planes, and systems of equations are covered in this extremely well-organized lesson. Composed of a series of mini-lessons, the instruction aims at explaining a different facet of solving systems of linear...
