2 One step equations Add Subtract Multiply Divide

3 Addition X + 5 = -9 X = X = X = X = X = 2

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

5 Answers!!! X = 7 X = 4 X = 3

6 Equations with subtraction X - 5 = 8 X = 8+5 X = X = X = X = 1

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

8 Answers!!! X = 6 X = 70 X = 10 X = -6

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

10 Try these on your paper. 4X = X = 9 6 = 5X 12X = 3

11 Answers!!! X = -4 X = -9 X = 6/5 X = 1/4

12 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

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

14 Answers!!! X = 27 X = -28 X = -3 X = 16

15 Write the following on your paper for a quiz grade. 1) _4X = 15 2) X/2 = -8 3) 9 - X = -1 4) X = 0 5) -X/3 = 4 6) X + 5 = 5 7) X - 4 = 4 8) -X = 5 9) X + 50 =-50 10) X/5 = -55
