What is a System of Equations?

1. What is a System of Equations?

So what happens if we want to compare more than one equation? Welcome to a 'system' of equations! Learn what one is, how to solve them and when they come up in real life.

How Do I Use a System of Equations?

2. How Do I Use a System of Equations?

There are a few classic algebra word problems, such as the one about two trains traveling at different speeds. In this lesson, you'll learn how to take a word problem and convert it into the system of equations that will allow you to find the answer using either substitution or elimination.

How to Solve a System of Linear Equations in Two Variables

3. How to Solve a System of Linear Equations in Two Variables

Watch this video lesson to learn how you can solve a system of linear equations in two variables by using the substitution method. Learn how easy it is to use on any linear system in two variables.

How to Solve a Linear System in Three Variables With a Solution

4. How to Solve a Linear System in Three Variables With a Solution

After watching this video lesson, you will be able to solve a linear system in three variables using the elimination method. Learn the simple operations that are needed to solve your system.

How to Solve a Linear System in Three Variables With No or Infinite Solutions

5. How to Solve a Linear System in Three Variables With No or Infinite Solutions

In this video lesson, you will learn to recognize when a linear system has no solution or an infinite number of solutions. You will also learn how to go about solving each of these types of systems.

Solving Systems of Equations by Graphing Calculator

6. Solving Systems of Equations by Graphing Calculator

Plotting the curves for a system of equations lets us see where the curves cross. These intersections are the solutions. In this lesson, we use a graphing calculator to enter functions, plot curves and find intersections.

Types of Systems of Equations

7. Types of Systems of Equations

This lesson will help you become familiar with the different types of systems of equations. After a quick review of the definition of a system of equations, we will look at each of the different types of systems and how to identify them.

Solving Systems of Equations with Fractions

8. Solving Systems of Equations with Fractions

Some students find equations with fractions intimidating, especially in a system of equations! Well, don't worry - in this lesson, you'll learn how to get rid of those pesky fractions and use algebra and graphs to solve systems of equations.
