Lesson 3.8: Solving Equations and Formulas
Students use the skills they have been developing and apply them to formulas and equations with multiple variable. One difficulty is often that the "answer" to a problem is not a single number but a collection of numbers and variables.
HW is p168:13-25 odd. 36.37

Lesson 3.6: Ratios and Proportions
This review lesson shows how to solve simple proportions (two ratios set equal to each other) using the cross-product technique. Two exampes are given below.
HW is p158:19-30 all, 31, 33

Lesson 3.5: Solving Equations with Variables on Both Sides
This is day one of this topic. The steps for solving equations with variables on both sides are:
Step1: Use the Distributive Property to "remove" grouping symbols.
Step 2: Combine like terms on each side of the equal side.
Step 3: Use the Addition and/or Subtraction Property of Equality to get variables on one side and numbers without variables on the other side.
Step 4: Use the Multiplication and/or Division Property of Equality to solve.
If the solution is false---- NO SOLUTION
If the solution is an identity--- ALL REAL NUMBERS
A class example can be found below:
HW is p152:17-39 odd
