This lesson is the second of five lessons in the Math 1 Systems of Linear Equations and Inequalities Unit.
24 substitution classwork problems
6 graphing review classwork problems
The lesson begins with simple substitution problems where one variable is already isolated and then moves on to more difficult problem where a variable will need to be isolated before beginning the substitution process.
The download for this lesson includes guided notes (with examples and class work problems), an answer key to the guided notes, and a SMART Notebook presentation that corresponds with the guided notes that includes a “Ticket Out the Door”.
