Ch 16: CEOE Middle Level/Intermediate Math: Systems of Equations

About This Chapter

Our instructors prepared this collection of lessons to assist you with taking the Certification Examinations for Oklahoma Educators (CEOE) Middle Level/Intermediate Math test. The subject matter covered here is systems of equations.

CEOE Middle Level/Intermediate Math: Systems of Equations - Chapter Summary

The lessons here are short videos meant as refreshers for you before you take your CEOE Math test. They will help you in answering test questions about things like:

  • Understanding what a system of equations is
  • Graphing a system of equations
  • Solving a system of equations by substitution
  • Using elimination to solve a system of equations
  • Working with a linear system in three variables with a solution, no solution or infinite solutions
  • Examining market equilibrium by using systems of linear equations
  • Looking at breakeven point using systems of linear equations
  • Reviewing how to solve 'and' and 'or' compound inequalities
  • Knowing about set notation, compound inequalities, and systems of inequalities

The videos average 5-10 minutes run time. They are hosted by Study.com subject matter experts, focus on one topic point and have a quiz at the end for self-assessment on the material just covered. If you need to go back and look at anything, you can use the video transcript or the convenient, keyword-based timeline tool to return to any specific point in the video. We have also provided a feature that allows you to ask a question directly to the expert if you so desire.
