Modeling 2 Step Equations

  1. 1. Modeling and Solving 2- operation EquationsYou can use algebra tiles to solve equations. = variable =1 = -1
  2. 2. 2y + 4 = 10Should I put things into groups first or should I tryto simplify the scales by removing like items from each side?
  3. 3. 2y + 2y = 10 4 =6Remove the four squares from each side to simplify the equation!
  4. 4. 2y = 6; separate your variables y=3 and split up the ones so that each variable has the same amount
  5. 5. Model and solve. 4x + 2 = -10
  6. 6. Solve – show your steps!4x - 10 = 34 -3n + 15 = 60
  7. 7. Solve – show all steps!n n 12 5 8 10 5 6
