One Step Equations

x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8

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.

x - 32 = 49

• x = 17
• x = 71
• x = 81
• x = 49

10x = 90

• x = 80
• x = 100
• x = 10
• x = 9

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

What is the inverse operation of division?

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides
• add 5 to both sides
• subtract 15 from both sides
• subtract 5 from both sides

m - 5 = -10

• -15
• 15
• -5
• 5

x - 15 = -20

• -5
• 5
• -35
• 35

The variable, k, is being divided by 11. How should you show your work to isolate the variable?

• Divide both sides by 11
• Multiply both sides by 11.
• Add 11 to both sides.
• Subtract 11 to both sides.
