Lesson: Applications on Systems of Linear Equations in Three Variables Mathematics

Start Practising

In this lesson, we will learn how to solve real-world problems using a system of linear equations in three variables.

Lesson Plan

Students will be able to

  • translate real-world problems into a system of linear equations and solve the system using substitution or elimination,
  • translate real-world problems into a system of linear equations and show that the system has no solutions,
  • translate real-world problems into a system of linear equations and show that the system has infinite solutions.
