This lesson is designed to review and reinforce three methods (graphing, substitution and elimination) of solving systems of linear equations. The students will work together and independently to find the solutions to systems of...

[Free Registration/Login Required] This flipchart provides guided practice with word problems involving systems of equations and gives a brief review on solving systems of equations.

[Free Registration/Login may be required to access all resource tools.] This lesson covers solving systems by multiplying one equation by a constant to eliminate a variable.

Practice the connection between the graphical representation of equations and their algebraic solutions. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

The purpose of this task is to give students the opportunity to make connections between equations and the geometry of the graphs. Aligns with A-REI.C.7and A-REI.D.10.

[Free Registration/Login may be required to access all resource tools.] This lesson covers determining the best method to solve a linear system.

This math site discusses how to solve a system of diferential equations.

Demonstration of how an augmented matrix is used to solve a system of linear equations.

[Free Registration/Login Required] This flipchart shows how to solve a system of equations using Cramer's Rule.

[Free Registration/Login may be required to access all resource tools.] Solve a system and use the result as a guide to identify its type.

The name linear comes from the fact that such an equation in two unknowns or variables represents a straight line. A set of such equations is called a system. This site explains all this and more.

Using determinants and Cramer's Rule, systems of two and three variables are solved step by step. Several examples are presented to demonstrate how Cramer's Rule is used.

The student will represent linear inequalities using equations, tables, and graphs. The student will solve linear inequalities using graphs or properties of equality, and determine whether or not a given point is a solution to a linear...

This Computer Algebra System (CAS) activity encourages students to investigate addition, subtraction, and multiplication of matrices. They find the inverse of a matrix. Students also solve a set of linear equations by using matrices.

Students solve a system of linear equations using the elimination method. The practice exercise is available in PDF format.

In this lesson, we'll learn to: Solve linear equations, Solve linear inequalities,and Recognize the conditions under which a linear equation has one solution, no solution, and infinitely many solutions.

A step by step of how to solve systems of linear equations using the row reduction method.

This interactive linear system solver allows you to enter two linear equations in general form and then plot the lines and find the answer using either substitution or elimination. The answer is presented with both methods accompanied by...

The purpose of this task is to test student skills at converting verbal statements into two algebraic equations and then solving those equations. Aligns with A-REI.A.1 and A-REI.C.

The practice exercise has students solve a system of linear equations and identify the graphs of the equations. The graphs are available in PDF format.

The practice exercise has students solve a system of linear equations and identify the graphs of the equations. The graphs are available in PDF format.

A way to solve a linear system algebraically is to use the substitution method. The substitution method functions by substituting the one y-value with the other. This resource explains this method by showing an example along with a video.

This illustrated math lesson shows how important levels of accuracy in measurement are. The answer can be different since a scale only accurately weighs to the nearest tenth of a gram instead of to the nearest hundredth of a gram. Aligns...
