# Ch 4: Solving Matrices & Determinants

Let us help you boost your understanding of how to solve mathematical equations using determinants and matrices. These lessons and quizzes can be used to help you earn the best score you can on an upcoming test or homework assignment.

## Solving Matrices & Determinants - Chapter Summary

In this chapter, you will learn about systems of equations and the many types of matrices that exist in the mathematical world. Our instructors will define reduced row-echelon forms and explain how to take a determinant of a matrix. Your study will continue with steps to solve systems of linear equations in two and three variables using determinants.

As you progress through the chapter, you will review matrix notation, and learn how to use rules to take the determinant of any size matrix. These lessons will teach you how to:

• Differentiate between and identify the different kinds of matrices
• Define reduced row-echelon form
• Take the determinant of a matrix
• Solve systems of linear equations using Cramer's Rule
• Explain the math operations you can do with matrices
• Use rules to work with higher-order determinants
• Solve inverse matrices
• Give examples of adjugate matrices

Use our chapter tests and lesson quizzes to gauge how well you understand the subject matter and where you may want to focus additional study. These materials are designed by professional instructors to ensure your learning experience is easy and engaging. If you need help as you work through the lessons, contact one of our instructors for assistance. All our lessons and quizzes are available to you anytime, and you can print the quizzes and transcripts for offline study.
