(20 13? Shaoxing) There is such a problem in China's ancient The Art of War and Mathematical Classics. Today, chickens and rabbits are in the same cage, with 35 heads above and 94 feet below. What are the geometric shapes of chickens and rabbits? The answer to this question is: 23 chickens and 0/2 rabbits. Now Xiao Min has adapted this question into: There are chickens and rabbits in the same cage, with 33 heads above and 88 feet below. What are the geometric shapes of chickens and rabbits? Then the answer at this time is: there are 22 chickens and rabbits.

Test site: the application of binary linear equations.

Analysis: If there are X chickens and Y rabbits, there are x+y=33 and 2x+4y=88. These two equations form a set of equations and find their solutions.

Solution: Solution: Suppose there are X chickens and Y rabbits. From the meaning of the question, you get:

x+y=332x+4y=88
