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 Using Matrices

6. Solving Systems of Equations Using Matrices

Systems of equations appear in all types of real-world applications. A nice way to solve these equations is to use matrix operations like row exchange, multiplication and addition. In this lesson, we show how this is done.

Independent System of Equations Examples

7. Independent System of Equations Examples

You may have heard of independent variables, but did you know that systems of equations can be independent? In this lesson, you'll explore some examples of independent systems of equations, including those found in algebraic equations and graphs.

Dependent System of Linear Equations Examples

8. Dependent System of Linear Equations Examples

What do you think of when you hear the word 'dependent?' You probably think of dependent children or someone that relies on another person. Well, equations can be dependent, too. In this lesson, you'll learn how to identify dependent systems of linear equations.
