  1. 2.2 Solving Multi-Step Equations Objective: SWBAT simplify Expressions Before Solving Linear Equations

  2. Mini Quiz 12 Solve -8x = -4x – 12 Solve 10 = 2n + 14

  3. Quick Review 1. Solve m = 45 2. Solve x = -50 3. Define additive inverse with one word. opposite 4. Define multiplicative inverse with one word. reciprocal

  4. Solving Equations Steps: Clear the equations of fractions and decimals Combine like terms on each side Get all the variables to one side Apply the correct inverse

  5. Solving Equations 1. 2x + x + 12 = 78 3x + 12 = 78 - 12 - 12 3x = 66 3 3 x = 22

  6. Solving Equations 2. 4x + 3x = 42 7x = 42 7 7 x = 6 6· 6· ·6

  7. Solving Equations 3. 4. 5. 48 3

  8. Solving Equations 6. 1.2x – 3.6 + 0.3x = 2.4 12x – 36 + 3x = 24 5 x – 36 = 24 5x = 60 15 15 x = 4

  9. Solving Equations 7. 2y + 9.75 – 7y = -5.25 8. 4 = 0.4(3d – 5) 9. 0.5(2x – 4) = -17 3 5 -15

  10. Wrap Up • Solving Multi-Step Equations • Clear the equations of fractions and decimals • Combine like terms on each side • Get all the variables to one side • Apply the correct inverse Assignment: P. 79 #1-37 EOO, 41-51 Odd, 58, 77 – 97 EOO Write your DLUQ and answer the question: How do you clear the fractions?
