Chapter 2 TEST Study Guide Scheduled for Monday December 8th -Solve Equations with Rational Numbers (Lesson 1 pgs 111-117) -Solve Two Step Equations (Lesson 2 pgs 121-128) – - Writing Two Step Equations from Word Problems (Lesson 3 pgs 129 136) -Problem Solving- Working Backwards (pg 137-140) -Solving Equations with Variables on Each side (Lesson 4 pgs 145-152) -***NEW*** Multi-Step Equations (Lesson 5 pgs 153-160) Solving Equations with Rational Numbers Solving Two-Step Equations Writing Two Step Equations from Word Problems Example #1- Amy needs to rent a car for 4 days. She also decides to purchase new windshield wipers for $16.99. If her bill at the Auto Rental Company comes to $366.99, how much is her rental car per day? “LET Step 1: YOU NEED A STATEMENT” in order to define your variable. We are trying to figure out the price of the rental car per day. Let x= amount of car per day Step 2: Amy rented the car for 4 days so 4 times x would represent the price of the rental. Step 3: She ADDED $16.99 to her total bill so we need to include + 16.99 Step 4: Write an equation 4x + 16.99 = 366.99 (her total) Step 5: Solve the equation using opposite operations on BOTH sides of = 4x + 16.99 = 366.99 (undo addition first) -16.99 -16.99
