Two motor pools sent vehicles to transport agricultural products, with the total number of vehicles being less than 18. The number of vehicles sent by the second motor pool is less than twice the number of vehicles sent by the first motor pool. If the first motor pool had sent 4 more vehicles, the number of vehicles sent by the first motor pool would have been less than the number of vehicles sent by the second motor pool.
