  1. 1. 1 Do Now OBJECTIVE: How do we solve equations with variables on both sides? Weekly Quiz #7
  2. 2. 2 Solve the following equations and SHOW YOUR CHECKS! a.) -2(x - 5) = -16 b.) -4x - 6 - 2x + 12 = -6 Weekly Quiz #7
  3. 3. 3
  4. 4. 4 Anticipatory Set Anticipatory Set: In a complete sentence, describe how you would use inverse operations to eliminate having variables on both sides. 49 + 3x = 4x + 14 How do we move terms from one side of the equation to another?
  5. 5. 5 ALGEBRA The Search for Unknowns Objective: Isolate the variable to find its value RULES 3.) Use inverse operations 1.) Keep the equation balanced 2.) Simplify each side by combining like terms and using the distributive property. 4x - 5 = 2x + 15
  6. 6. 6 4x - 5 = 2x + 15
  7. 7. 7 ALGEBRA The Search for Unknowns Objective: Isolate the variable to find its value RULES 3.) Use inverse operations 1.) Keep the equation balanced 2.) Simplify each side by combining like terms and using the distributive property. 9x = 6x + 21
  8. 8. 8 ALGEBRA The Search for Unknowns Objective: Isolate the variable to find its value RULES 3.) Use inverse operations 1.) Keep the equation balanced 2.) Simplify each side by combining like terms and using the distributive property. 2k = 18 - 4k
  9. 9. 9 ALGEBRA The Search for Unknowns Objective: Isolate the variable to find its value RULES 3.) Use inverse operations 1.) Keep the equation balanced 2.) Simplify each side by combining like terms and using the distributive property. -5y - 14 = 2y
  10. 10. 10 -5y - 14 = 2y
  11. 11. 11 ALGEBRA The Search for Unknowns Objective: Isolate the variable to find its value RULES 3.) Use inverse operations 1.) Keep the equation balanced 2.) Simplify each side by combining like terms and using the distributive property. 3x = 5x + 18
  12. 12. 12 ALGEBRA The Search for Unknowns Objective: Isolate the variable to find its value RULES 3.) Use inverse operations 1.) Keep the equation balanced 2.) Simplify each side by combining like terms and using the distributive property. 8w - 9 = 3w + 16
  13. 13. 13 ALGEBRA The Search for Unknowns Objective: Isolate the variable to find its value RULES 3.) Use inverse operations 1.) Keep the equation balanced 2.) Simplify each side by combining like terms and using the distributive property. -12x - 10 = -6x + 14
  14. 14. 14 -12x - 10 = -6x + 14
  15. 15. 15 ALGEBRA The Search for Unknowns Objective: Isolate the variable to find its value RULES 3.) Use inverse operations 1.) Keep the equation balanced 2.) Simplify each side by combining like terms and using the distributive property. 49 - 3x = 4x + 14
  16. 16. 16 Before You Leave Describe, in a complete sentence, how you would decide which variable term to add or subtract on both sides of the equation -3x + 7 = 4x - 9.
