One Step Equation Word Problems Addition Subtraction

Solve for x
17 = x + 3

• x = 20

• x = 14

• x = 13

• x = 19

x + 24 = 44

• x = -20

• x = 68

• x = 20

• x = -68

To solve the equation
x + 5 = 8
 I would ....

• subtract 5 from x

• subtract 5 from both sides

• subtract 5 from one side and add 5 to the other

• add 5 to both sides

Javier has saved $55 toward the purchase of an IPOD. The IPOD costs $145. Which equation represents the amount Javier needs to save to by the IPOD?
