1. Lesson 1-5: Solving Equations
Objectives:
(Do not write)
Students will solve equations involving simplifying, combining like terms, the distributive property, and variables on both sides.

2. The Golden Rule: Whatever you do to one side you must do to the other
Fraction equations give students most trouble: you have two choices
a) Use the fractions
Get common denominator
move variable to one side and constants to other
Then multiply by reciprical

3. b) get rid of fractions using LCD
LCD is 8 so multiply all terms by 8
Simplify
move variable to one side and constants to other
Then divide

4. Explain: Which method do you prefer? why?

5. Follow “Tips for solving equations (inequalities)” to solve the following
Problem 1: 5m m = 6m -1-m

6. Problem 2:
4(3x – 8) = 11x – 8 + x

7. Problem 3:

8. Answers 1) m = -8 2) No solution 3)
