one-step equations

17 = x + 3

• x = 20
• x = 14
• x = 13
• x = 19

x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8

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?

Which equation has x = 5 as the solution?

• x + 15 = 10
• 2x = 5
• 2x = 10

Which equation has x = 5 as the solution?

• x + 15 = 10
• 2x = 5
• 2x = 10

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
