Tuesday, 1/26/16: Lesson 8-4, Solving Systems Using the Elimination Method

Tonight's homework is p.254 (4-6).  Students are to solve these systems in their spiral homework notebook.  Parents, we modeled two more problems today in class; students should have been recording all of the writing steps.  (These problems are very writing-intensive.)

Our next test is on solving equations in one variable and systems, and it is Wednesday, 2/3.  The material on it:

• equations (Lessons 7-1, 7-2, 7-3, and 7-4)
• solving systems by substitution (Lesson 8-2)
• solving systems by elimination (Lesson 8-3)

Additionally, Lesson 8-1 should be reviewed, because that involved graphing and set the stage for solving by substitution and elimination.  (We used an excellent worksheet instead of the text for graphing, but the lesson details that aspect.)
