Ch 28: MTTC Math (Secondary): Systems of Equations

About This Chapter

Develop your understanding of systems of equations so that you can answer pertinent questions on the MTTC Math (Secondary) examination. This chapter includes online video lessons that you can use as tutorials prior to taking the test.

MTTC Math (Secondary) Systems of Equations - Chapter Summary

Revisit systems of equations throughout this chapter's educational video lessons. In addition to helping you to set up a system of equations, the lessons outline numerous methods for solving them. The videos also compare a system of equations to real-world examples and provide you with several practice opportunities. In preparation for passing the MTTC Math (Secondary) examination, watch the videos in order to:

  • Define and graph a system of equations
  • Use the substitution and elimination methods to solve systems of equations
  • Identify methods for solving a linear system in two variables
  • Solve a system of equations with three variables with a solution, or three variables with infinite or no solutions

Seasoned instructors share their knowledge of systems of equations as you get set for the MTTC Math (Secondary) examination. Watch this chapter's self-paced videos for review purposes, and you could possibly even learn new information. In addition to video tags that allow you to locate facts in different parts of the videos, the online lessons include written transcripts and self-assessment quizzes.
