## Who's it for?

This chapter of our high school algebra II tutoring solution will benefit any student who is trying to learn systems of linear equations and earn better grades. This resource can help students including those who:

- Struggle with understanding how to solve a system of linear equations using two or three variables or solve a system with an infinite solution or any other systems of linear equations topic
- Have limited time for studying
- Want a cost effective way to supplement their math learning
- Prefer learning math visually
- Find themselves failing or close to failing their systems of linear equations unit
- Cope with ADD or ADHD
- Want to get ahead in high school algebra II
- Don't have access to their math teacher outside of class

## Why it works:

**Engaging Tutors:**We make learning about systems of linear equations simple and fun.**Cost Efficient:**For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.**Consistent High Quality:**Unlike a live algebra II tutor, these video lessons are thoroughly reviewed.**Convenient:**Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about systems of linear equations on the go!**Learn at Your Pace:**You can pause and rewatch lessons as often as you'd like, until you master the material.

## Learning Objectives

- Define systems of equations.
- Change stories into equations to solve.
- Solve linear systems in two or three variables.
- Solve linear systems in three variables with no or infinite solutions.

### 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.

### 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.

### 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.

### 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.

### 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.

### 6. Gaussian Elimination: Method & Examples

This lesson introduces Gaussian elimination, a method for efficiently solving systems of linear equations using certain operations to reduce a matrix.

### 7. Solving Equations with the Substitution Method: Algebra Examples & Overview

What does the substitution method have to do with substitute teachers? Learn why you should love substitutes. Also learn how substitutes make your life easier when it comes to solving sets of equations.

### 8. System of Linear Equations: Definition & Examples

A system of linear equations can come in handy when we come across problems where we have more than one quantity to find. In this lesson, we'll learn how to define a system of linear equations and look at examples.
