of wheeled backpacks in the new shipment was twice the number of
wheeled backpacks already in stock, and the number of backpacks without

without wheels already in stock. After the new shipment arrived, there
were 330 backpacks in the store. Before the new shipment, there were x
wheeled backpacks and y backpacks without wheels. Which of the
