### About This Chapter

## Ohio EOCE Algebra I: Systems of Equations & Matrices- Chapter Summary

The Ohio End of Course Exam (EOCE) covering algebra I will contain several questions assessing you on the subject of systems of equations and matrices. You can study for these questions by going through each of the short video lessons contained within this chapter. The lessons will cover topics such as:

- System of equations
- Using system of equations
- The definition of a matrix
- Matrix notation, equal matrices and matrix operations
- Taking the determinant of a matrix

After you've completed all of the lessons, you can test your knowledge of some of the topics by taking the practice quizzes in this chapter. Once you have finished the whole chapter, complete the comprehensive exam and see where you need additional review. You'll have a much better chance of doing well when you take the actual EOCE exam after completing our study guide!

### 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. What is a Matrix?

As math gets more and more complicated and there become more and more numbers flying around, it becomes really handy to put all these numbers in a nice organized grid... hello matrices! Learn about what they are and why there are used.

### 4. Matrix Notation, Equal Matrices & Math Operations with Matrices

Watch this video lesson to learn about the basics of matrices and what kinds of math operations you can do with them. Also learn how to determine whether two matrices are the same or not.

### 5. How to Take a Determinant of a Matrix

Matrices are incredibly powerful and can help you do all sorts of things, but one of the most basic (and surprisingly helpful) operations you can perform on one is to take its determinant. Learn how to do that here!
