This lesson is the third of five lessons in the Math 1 Systems of Linear Equations and Inequalities Unit.
18 elimination classwork problems
The lesson begins with simple elimination problems where one of the variable's automatically eliminates and then moves on to more difficult problem where a one of the equations will need to be manipulated before eliminating a variable.
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”.
