Lesson 8.3 Solving Systems of Linear Equations by Elimination

Lesson 8.3 video link here.

So far, you've seen how to solve systems of linear equations graphically, and by substitution. This lesson uses the fact that entire equations can be added or subtracted to reduce the number of variables involved.

 

 


In Lesson 8.3, you will learn about

  • solving systems of linear equations by elimination

  • solving systems with 0 or an infinite number of solutions algebraically
