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
