  1. Mr. DeBruzzi’s Math Class Four Steps to Solving Equations

  2. 1. ID the variable 4x + 3 = 2 - 5x

  3. subtracted multiplied 2. What’s happening to it? 4x + 3 = 2 - 5x

  4. 3. How do I UNDO what’s happening? Add 5x to each side 4x + 3 = 2 - 5x + 5x + 5x

  5. 4. OK -- Do it! 4x + 3 = 2 - 5x + 5x + 5x 9x + 3 = 2

  6. 4. OK -- Do it! 9x + 3 = 2 - 3 - 3 9x = - 1

  7. 4. OK -- Do it! 9x = - 1 /9 /9 x = - 1/9
