Problem: There are some animals in a garden. Each of them is a crane with two legs or a turtle with four legs.  Takahashi says: "there are X animals in total in the garden, and they have Y legs in total." Determine whether there is a combination of numbers of cranes and turtles in which this statement is correct.
