9 3

Solution:

Analyzing Question: Let the total number of sweets prepared is  n and the total participant is x, n sweets is given for x friends with 6 each. 6x=n n-23 sweets is given for x+1 friends with 5 each.



5(x+1)=n-23 5x-5=n-23 Before have more one participant, 6 x=n. After have one more participant, Therefore, 5x-5=n-23 Sub equation {6x=n} into {5x-5=n-23} 5x-5=6x-23 18=x As conclusion, total number of sweets, n=6x Sub x=18 into n=6x 

n=618 n=108

Total number of sweets had prepared is 108.
