1 Step Eq. Practice

x + 4 = 20

• 16

• 18

• 24

• 80

What is the solution of the equation? 
8 = x + 1

• 9
• 7
• -7
• -9

17 = x + 3

• x = 20
• x = 14
• x = 13
• x = 19

x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8

4 + b = 30

• -34
• 34
• -26
• 26

x - 32 = 49

• x = 17
• x = 71
• x = 81
• x = 49

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 
• Subtract 62 from each side.
• Multiply each side by 62.
• Add 123 to each side.

10x = 90

• x = 80
• x = 100
• x = 10
• x = 9

6b = 30

• b = 36

• b = 24

• b = 180

• b= 5

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9
• x = 3
