Lesson 8.2: Solving Systems of Linear Equations by Substitution

Lesson 8.2 video link here.

Graphically determining the solution to a system of linear equations is a good visual method, but drawing graphs can take time and usually the solutions are only approximations. This lesson focuses on one algebraic method of solving linear systems of equations.


In Lesson 8.2, you will learn about

  • solving linear systems of equations using substitution
