Marcus and Leon each pick a pumpkin from the pumpkin patch. Marcus's pumpkin weighs 6 pounds more than twice the weight of Leon's pumpkin. Another way to view this is that Marcus's pumpkin weighs 22 pounds less than 4 times the weight of Leon's pumpkin. Which equation represents the situation?

• 2w + 6 = 4w – 22

• 2w – 22 = 4w + 6

• 6w + 2 = 4w + 22

• 4w + 22 = 2w – 6
