Equations

x - 8 = 17

Add 8 to both sides leaving you with x = 25

4x = 12

Divide 4 on both sides leaving you with x = 3

4x - 15 = 17

First you must add 15 to both sides to get 4x = 32 Then divide both sides by 4 and get x = 8

Two step equations mean you must.....

Get rid of the addition or subtraction first and then get rid of the multiplication or division second (by doing the opposite on both sides)

x/12 = 36

Multiply 12 on both sides leaving you with x = 432

3x + 12 = 36

Subtract 12 from both sides and get 3x = 24 Then divide by 3 on both sides and get x = 8

x + 7 = 12

Subtract 7 from both sides leaving you with x = 5

x/-2 - 15 = 15

x = -15

34 - x = 15

x = 19

18 = 6x

x = 3

20 = 3x + 2

x = 6

8x = 64

x = 8

98 = 12x + 2

x = 8

x - 6 = 78

x = 84

6x - 13 = 41

x = 9
