One Step Equations Add Subtract Models

Solve for x.

-6x = 30

• x = - 5

• x = 24

• x = 5

• x = 36

36 = 9b

• 4

• -27

• -45

• -4

Solve for h.

h - 4 = 397

• h = -401

• h = 401

• h = -393

• h = 393

Drew has saved $55 toward the purchase of AirPods. The AirPods cost $145. Which equation represents the amount Drew still needs to save to buy the Airpods?

• 55 + x = 145

• 145x = 55

• 55 - x = 145

• 145 (55) = x

Charlie had an unknown amount of candy. He gave ten pieces to Ava and is left with 24 pieces. Which equation should I use to solve for how many pieces he started with?

• x +10 = 24

• x - 10 = 24

• 10x = 24

• x + 24 = 10

Which equation models this situation? Last week, Tina worked a total of 35 hours. She worked the same number of hours each day for 5 days. How many hours did she work each day?

• h - 5 = 35

• h + 5 = 35

• 5h = 35

• h/5 = 35
