Students will set up systems of equations from word problems and apply the method of elimination to solve them. Lesson The lesson will begin with a warm-up. Students will be given three Summary minutes to complete a system of equations using elimination by (one addition or subtraction. After the warm-up, students will be paragraph presented with a system that they cannot solved by simply adding or maximum) subtracting the equations. We will discuss the reasons why they cannot solve it. Students will learn through examples that they will need to multiple either one or both equations by a factor in order to be able to make the coefficients of one of the variables opposite of each other. From here they will be able to add or subtract the equations. They will work in groups to solve word problems where they will need to set up a system of equations and solve by elimination. HW The homework will come from the book. Students will be assigned to do page 455 #9-17 odd, 37, 38.
