Solving Systems of Equations by Substitution

Crash Course Video Lesson

Crash Course Video Lesson (Spanish)

Common Misconceptions to Look Out For

• Confusing when to use substitution vs. elimination
• Mistaking “no solution” and “infinite solutions” cases
• Errors in isolating a variable or solving for the remaining variable

Differentiation Tips

• Scaffolding: Start with systems where one equation already has a variable isolated to practice the substitution step.
• Advanced Learners: Include word problems that require setting up and solving systems to apply math in real-world situations.
