One Step Equations

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
