Sophia: Using Elementary Row Operations to Solve Systems of Equations: Lesson 4

With 30 problems, each accompanied by a blank graph, pupils get thorough practice solving systems of equations by graphing and finding the point of intersection. Answers are provided in coordinate form.

Lets keep the system working and show learners the three ways to solve linear systems of equations. Each method includes step-by-step instructions to work their way through the problem. The same problem is used for each method to show...

Eliminate the obvious. A series of slides presents algebra classes with step-by-step procedures for solving systems of equations using the elimination method. It provides an introduction to the elimination method for...

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...

Sal begins this video by "massaging the equations slightly to prepare them for elimination." The equations won't be the only relaxed part of this lesson, which introduces the concept of multiplication to systems of equations. Viewers...

This lesson presents how to use elementary row operations to solve for a system of linear equations. It is 1 of 4 in the series titled "Using Elementary Row Operations to Solve for Systems of Equations."

This video lesson demonstrates how to solve a system of linear equations by using matrix row operations. Students can check their understanding with an assessment.

Secret codes are so much fun, and a great way to practice nearly any math skill. Let your class become code breakers as they investigate inverse matrices. They use TI-Nspire technology to solve systems of equations which help them crack...

This lesson presents how to use elementary row operations to solve for a system of linear equations.

Explore the concept of systems of equations in two variables and use matrices to solve them. Young mathematicians enter coefficients and constants into a matrix and then solve using row reduction. Instructions on how to use the shortcut...
