  21. Solve Two Step Equations - 500 Board Answer

  22. Solve Two Step Equations - 500 No Algebra Tiles here 6 Get rid of fractions by multiplying by LCD ____ 6   6  6 4x + 3 = -18 Finish – 3 – 3 4x = -21 4 4 Board

  23. Solve Other Equations - 100 Solve: 2(x + 3) = 10 Board Answer

  24. Solve Other Equations - 100 Solve: 2(x + 3) = 10 Algebra Tiles 2(x + 3) = 10 What is this equation? Algebra 2(x + 3) = 10 Get rid of 6 yellows 2x + 6 = 10 – 6 – 6 2x = 4 Both Sides 2 2 Cancel What is this equation? x = 2 Separate the squares Board x = 2

  25. Solve Other Equations - 200 Solve: 3(x – 4) = -15 Board Answer

  26. Solve Other Equations - 200 Solve: 3(x – 4) = -15 Algebra Tiles 3(x – 4 ) = -15 What is this equation? Algebra 3(x – 4) = -15 Get rid of 12 reds 3x – 12 = -15 +12 +12 3x = -3 Both Sides 3 3 Cancel What is this equation? x = -1 Separate the squares Board x = -1
