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.

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

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

Explain: Which method do you prefer? why?

Follow “Tips for solving equations (inequalities)” to solve the following Problem 1: 5m -17- 2m = 6m -1-m
