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

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.
