  1. BALANCING 2 AIM: To solve equations with variables on both sides

  2. T T T T 5 T T 11 4T + 5 = 2T + 11

  3. T T T 5 T 11 4T + 5 = 2T + 11 3T + 5 = T + 11

  4. T T 511 4T + 5 = 2T + 11 3T + 5 = T + 11 2T + 5 = 11 T   2  +5  11 T   2  -5  11 T = 3

  5. T T T T T 2 T T 17 5T + 2 = 2T + 17

  6. T T T T 2 T 17 5T + 2 = 2T + 17 4T + 2 = T + 17

  7. T T T 217 5T + 2 = 2T + 17 4T + 2 = T + 17 3T + 2 = 17 T   3  +2  17 T   3  -2  17 T = 5

  8. T T T T T -10 T 18 5T - 10 = T + 18

  9. T T T T -1018 5T - 10 = T + 18 4T - 10 = 18 T   4  -10  18 T   4  +10  18 T = 7

  10. How many Ts can I take from each side? T T T T T T -15 T T T 3 6T - 15 = 3T + 3

  11. How many Ts can I take from each side? T T T -153 6T - 15 = 3T + 3 3T - 15 = 3 T   3  -15  3 T   3  +15  3 T = 6

  12. Now try these. Draw a diagram and use it to help you solve these equations. • 4T + 1 = 2T + 9 • 5T + 3 = 2T + 21 • 3T + 8 = T + 12 • 8T - 1 = 4T + 7 • 6T - 11 = T + 14 • 7T + 4 = 3T + 24 • 5T - 6 = 3T + 1 T = 4 T = 6 T = 2 T = 2 T = 5 T = 5 T = 3.5
