  1. Solving Two Step Equations Jennifer Mellske Spring 2012

  2. Do Now • Solve for x: • (-5) + (-4) = x • 3x = 24 • x + 15 = 25

  3. TLW demonstrate knowledge on how to solve two step equations involving integers • Example 1a. Do Undo 4x + 8 = 20 - 8 - 8 4x = 12 4 4 x = 3

  4. TLW demonstrate knowledge on how to solve two step equations involving integers • Example 1b. Do Undo 20 = 4x + 8 - 8 - 8 12 = 4x 4 4 3 = x

  5. TLW demonstrate knowledge on how to solve two step equations involving integers • Example 2. Do Undo 6x – 12 = 36 + 12 + 12 6x = 48 6 6 x = 8

  6. TLW demonstrate knowledge on how to solve two step equations involving integers • Example 2. Do Undo x – 1 = 4 2 + 1 + 1 x = 5 2 2 ∙ ∙ 2 x = 10

  7. TLW demonstrate knowledge on how to solve two step equations involving integers • Example 2. Do Undo -7x + 9 = 49 - 9 - 9 - 7x = 40 - 7 - 7 x = -5

  8. Exit Slip • Solve for x: 27 = 8x - 13
