This lesson explains how we might represent an equation in terms of more than one variable. It is 2 of 5 in the series titled "Equations of Several Variables."

In this exercise, learners will use inverse operations to solve the equations for the unknown variable, or for the designated variable if there is more than one. Aligns with A-CED.A.4.

The purpose of this visualization task is to help provide geometric intuition for the algebraic process called ''completing the square.'' Aligns with HSA-REI.B.4.a.

[Free Registration/Login may be required to access all resource tools.] In this lesson students learn how to solve compound inequalities. Students watch a video tutorial, explore guided notes and attempt practice problems.

It is often desirable or even necessary to use more than one variable to model a situation in many fields. When this is the case, we write and solve a system of equations in order to answer questions about the situation.

Spanish content. Clear step by step directions and examples on how to solve inequalities with one variable. A great supplement in algebra class for the Spanish speaking student.

Gain an understanding of how to solve linear equations by viewing an example and a video lesson. [3:01]

For this task, learners are shown the graphs of two equations, with areas bounded by their lines and intersections shaded in different colors. They are asked to write a system of equations or inequalities for each shaded area and explain...
