Solve a system of equations using elimination
Solve a system of equations using elimination
What you'll learn
- Solve systems of three linear equations in three variables using the elimination method with 80% accuracy on a summative assessment.
- Identify and explain the conditions under which the elimination method is most efficient for solving a given system of linear equations in a written response with complete justification.
- Apply the elimination method to solve real-world problems modeled by systems of linear equations, demonstrating correct setup and solution procedures in a group project.
- Analyze a system of equations to determine if it has a unique solution, no solution, or infinitely many solutions after attempting to solve by elimination, justifying the conclusion based on the resulting equations.
