Student Outcomes

  • Students create systems of equations that have the same solution set as a given system.
  • Students understand that adding a multiple of one equation to another creates a new system of two linear equations with the same solution set as the original system.  This property provides a justification for a method to solve a system of two linear equations algebraically.
