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
