AIM: How do we solve systems using substitution?
Topic: Solving systems algebraically
AIM: What are special types of systems?
DO NOW:
Mini-Lesson/Guided PracticeYou can solve a system of equations byGraphing when the solution containsIntegers or when you have a graphingcalculator. Another method for solving systems of equations is the substitution method. By replacing one variable with an equivalent expression containing the other variable, you can
