[Free Registration/Login may be required to access all resource tools.] Isolate and substitute for one variable to solve systems of equations in two variables.

In this lesson, students make observations about the motion of a boat going up and down the river. They will solve the system of equations algebraically and graphically.

This task requires learners to recognize the pairs of linear equations in two variables that would be used to solve a given system of equations. Aligns with A-CED.A.3.

Take a closer look at the SAT Math Test. Math questions on the test fall into different categories called "domains." One of these domains is Heart of Algebra. It focuses strongly on algebra -- especially on the areas of the subject that...

Eighth graders are given a linear equation and instructed to find a second linear equation in order to make a system of equations that fits different criteria related to its possible solutions. Aligns with 8.EE.C.8.

In Spanish. Learn the algebraic language to represent and solve systems of two linear equations with two unknowns.

This college site offers a variety of problems and answers. Problems are divided into topic areas for easy access. Also offers quizzes with each topic.

[Free Registration/Login Required] Students will learn how to estimate what the solution to a system of linear equation is by graphing.
