GED Math Chapter 10: Systems and Basic Matrix Operations Lesson 2

Hello, welcome to lesson 2 on systems.  I’m going to teach you a much better way to solve systems compared to the last lesson.  The substitution method is one of the best ways to solve systems so you want to really work hard and master the skill.  Systems are everywhere in algebra and if you continue to study math you will see systems again and again.

Things to focus on this lesson:

• how to solve for one variable in a two variable equation
• the steps to solve a system with the substitution method
• how to verify a solution to a system

Chapter 10 Lesson 2

Solve Systems Substitution Method

How often do you study for the GED? You should try to study at least 30 min a day.

Nice job you know that much more about systems.   At this point in the course you should be able to:

  • Solve a system by graphing
  • Solve a system by the substitution method
  • Understand the types of solutions a system can have

OK, we are ready to start the next lesson on systems.

Hello John, I am writing to thank you. During the Summer I took and passed all of my GED courses with the exception of the Math test. I found your free math course online and listened and watched all of the videos, trying to educate myself utilizing the tools and tips that you provided. I have to admit, it was very overwhelming and at times I felt as though I was being taught in a foreign language. I scheduled my re-test earlier this week and I passed. Thank you from the bottom of my heart. It took me 22 years to feel confident enough to achieve this goal and I am forever grateful to you for offering this information online. You are heaven sent! Now I can apply for better paying jobs and attend college. Thank you, thank you, thank you for helping others change their lives for the better!!” Sincerely, Alicia
