Using Reasoning to Understand Equations & Solutions

1. Using Reasoning to Understand Equations & Solutions

To solve equations, we isolate the desired variable on one side of the equation using a set of rules. This lesson will explain the reasoning behind these rules and allow us to see why we can use them.

How to Solve a System of Equations by Substitution

2. How to Solve a System of Equations by Substitution

Watch this video lesson to learn how you can solve a system of equations by using the substitution method. Learn the key to using the substitution method and take a quiz to practice your new skills.

Solving and Graphing Two-Variable Inequalities

3. Solving and Graphing Two-Variable Inequalities

With an inequality like y < 2x - 3, where do we start? We can look at y = 2x - 3 and graph it. We can use the graph to define all of the possible solutions.

How to Solve Linear Equations By Graphing

4. How to Solve Linear Equations By Graphing

This lesson will give a quick review of systems of linear equations and their solutions. We will then look at taking an example through a step-by-step process that allows us to solve a system of linear equations by graphing.

How to Solve Systems of Linear Equations by Graphing

5. How to Solve Systems of Linear Equations by Graphing

Systems of linear equations are important in many branches of math and science, so knowing how to solve them is important. In this lesson, learn one way to find the solution of a system of linear equations by graphing.
