Solving one-step equations

Solve the equation:

4p = 16

• p = 12

• p = 64

• p = -4

• p = 4

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

17 = x + 3

• x = 20
• x = 14
• x = 13
• x = 19

10x = 90

• x = 900

• x = 100

• x = 10

• x = 9

Solve for the missing variable:

• m = 5
• m = 1/5
• m = 25
• m = 55

x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8
