Xiao Ming, Xiao Hong and Xiao Jun have 49 books. Xiaoming has four more books than Xiaohong, and Xiaohong has six more books than Xiaojun. How many books do they each have?
Solution: If Xiaojun has X books, Xiaohong has (x+6) books and Xiaoming has (x+6+4) books, according to the meaning of the question:
x+(x+6)+(x+6+4)=49
3x+ 16=49
3x=33
x= 1 1
Xiaohong: 1 1+6= 17 (Ben)
Xiao Ming: 17+4=2 1 (Ben)
