### About This Chapter

## MTEL Middle School Mathematics: Linear Equations - Chapter Summary

This chapter serves as a resource in your studies for the MTEL Middle School Mathematics exam. Use it to develop your knowledge of linear equations and their uses. These lessons will define linear equations and detail the following:

- Writing linear equations and using them to solve problems
- Using and putting word problems into the system of equations
- Solving linear equations with the distributive property or literal coefficients
- Forms of linear equations, including standard and intercept
- Steps necessary for solving simultaneous linear equations

When you view the brief video lessons, keep in mind they are also available as full transcriptions that enable you to process the information at your own pace. If you have any difficulties understanding any of the content, you may reach out to one of our expert mathematicians for assistance.

### 1. What is a Linear Equation?

Most cars won't be able to run for more than 250,000 miles, so how much longer will your car live? Linear Equations are the most basic kind of algebraic function and can help you answer questions exactly like this. Learn about what they look like, how they come up in your life and why they are powerful tools.

### 2. How to Write a Linear Equation

Simply knowing how to take a linear equation and graph it is only half of the battle. You should also be able to come up with the equation if you're given the right information.

### 3. Problem solving using Linear Equations

From sale prices to trip distances, many real life problems can be solved using linear equations. In this lesson, we'll practice translating word problems into linear equations, then solving the problems.

### 4. Applying the Distributive Property to Linear Equations

When it comes to linear equations, there are certain steps you have to take to solve them. One of them is the application of the distributive property when you see a pair of parentheses. Watch this video lesson to learn how.

### 5. Solving Linear Equations with Literal Coefficients

In this lesson, we'll literally learn about literal coefficients. We'll look at how to solve linear equations that contain literal coefficients and practice solving several problems.

### 6. Linear Equations: Intercepts, Standard Form and Graphing

Do you know what to do if an equation doesn't look like y=mx+b?! If not, then this video is for you. Chances are the equation is in standard form, so we'll learn how to use standard form equations, how to graph them and why they can be helpful.

### 7. 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.

### 8. Solving Simultaneous Linear Equations

In this video lesson, you will learn how to solve simultaneous linear equations or a system of linear equations. Learn the steps you need to take to solve any such system using the Gaussian elimination method.
