  4. 4. 4
  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 by combining like terms. 3(x + 4) = 36
  6. 6. 6 3(x + 4) = 36 CHECK
  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 by combining like terms. -6(x + 3) = 12
  8. 8. 8 CHECK -6(x + 3) = 12
  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 by combining like terms. 2(x - 4) = 40
  10. 10. 10 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 by combining like terms. -4(x - 4) = 20
  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 by combining like terms. -30 = -5(x + 3)
  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 by combining like terms. -30 = -6(x + 5)
