  1. One step equations Add Subtract Multiply Divide

  2. Addition • X + 5 = -9 • X + 5 - 5 = -9 -5 • X = -14 • -6 + X = -4 • -6 + 6 + X = -4 + 6 • X = 2

  3. Try the following on your paper. • 10 = X + 3 • 5 + X = 9 • 6 = 3 + X

  4. Answers!!! • X = 7 • X = 4 • X = 3

  5. Equations with subtraction • X - 5 = 8 • X - 5 + 5 = 8+5 • X = 13 • 5 - X = 6 • 5 - 5 + X = 6 - 5 • X = 1

  6. Try the following on your paper. • X - 7 = -1 • X - 4 = 66 • 8 = X - 2 • -8 = X - 2

  7. Answers!!! • X = 6 • X = 70 • X = 10 • X = -6

  8. Multiplication of Equations • 3X = -9 3X/3 = -9/3 • X = -3 • -5X = -40 • -5X/-5 = -40/-5 • X = 8

  9. Try these on your paper. • 4X = -16 • -1X = 9 • 6 = 5X • 12X = 3

  10. Answers!!! • X = -4 • X = -9 • X = 6/5 • X = 1/4

  11. Division of Equations • 1/2X = 4 • (2/1)1/2X = 4(2) • X = 8 • -3/4X = 6 • (-4/3)(-3/4)X = 6(-4/3) • X = -8

  12. Try these on your paper. • X/3 = 9 • -X/4 = 7 • 1/3X = -1 • 4 = X/4

  13. Answers!!! • X = 27 • X = -28 • X = -3 • X = 16

  14. Write the following on your paper for a quiz grade. • _4X = 15 • X/2 = -8 • 9 - X = -1 • -12 + X = 0 • -X/3 = 4 X + 5 = 5 X - 4 = 4 -X = 5 X + 50 =-50 X/5 = -55
