  1. x – (-2) = -13 Warm up: solve for x

  2. Inverse Operations LEQ: What are inverse operations and how do we use them to solve one step equations?

  3. Inverse operations are operations that “undo” each other • For addition and subtraction, inverses are operations that we perform to a number to get 0 • For multiplication and addition, inverses are operations that we perform to a number to get 1

  4. Addition and subtraction are inverses of each other • Addition undoes subtraction • Subtraction undoes addition • Multiplication and Division are inverses of each other • Multiplication undoes division • Division undoes multiplication

  5. 1.) 3 ? = 1 The multiplicative inverse of 3 is 1/3. 2.) 3 +___=0 The additive inverse of 3 is -3. 3.) What is the multiplicative inverse of 1/8? 4.) What is the additive inverse of -6? Examples

  6. Ex. 1: 1 + x = 10 Ex. 2: y – 4 = 12 Ex. 3: x + 2 = -13 Ex. 4: x + -2 = -13 Let’s solve equations using inverse properties of addition and subtraction only

  7. 1.) 12 + y = 15 4.) -12 = w + -7 2.) 6 + x = -12 3.) 9 = r – 10 On your own:
