One step equations Add Subtract Multiply Divide By: Jennifer Del-Castillo John F. Kennedy Middle School

3
Addition X + 5 = -9 X + 5 - 5 = -9 -5 X = -14 -6 + X = -4 -6 + 6 + X = -4 + 6 X = 2

4
Try the following on your paper. 10 = X + 3 5 + X = 9 6 = 3 + X

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

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

7
Try the following on your paper. X - 7 = -1 X - 4 = 66 8 = X - 2 -8 = 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 = -40 -5X/-5 = -40/-5 X = 8

10
Try these on your paper. 4X = -16 -1X = 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) -12 + 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
