Solving One Step Equations with Models

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.

y - 4.6 = 12

• 16.6
• 5.8
• 7.4
• Answer not Given

10x = 90

• x = 80
• x = 100
• x = 10
• x = 9

5.    6b = 30

• x = 36
• x = 24
• x = 180
• x = 5

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9
• x = 3

y/-5 = 20

• y = 100
• y = -4
• y = -100
• y = -15
