Monday, 1/25/16: Lesson 8-3, Solving Systems of Linear Equations by the Addition / Subtraction Method

Tonight's homework is p.246 (3-5) & p.248 (8-10).  Students should use their homework spiral notebooks for this work, as it is very writing-intensive.  Please see the post for last Wednesday, 1/20/16, for all of the available resources I'm suggesting for home.  Also please know that we modeled two problems in class today; students should have copied down all of the writing.

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.)
