Answer:
multiples of 9: 9, 18, 27, 36, 45, 54, 63,72, 81, 90, 99, 108, etc.
factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
Step-by-step explanation:
9,18, and 36
9*4=36 and 9*1=9
18*2=36 and 9*2=18
36*1=36 and 9*4=36
The problem statement tells us ...
8x = y +3
7x = y -4
Subtracting the second equation from the first gives ...
x = 7
Then ...
y = 7x +4 = 7·7 +4 = 53
There are 7 people, and 53 coins are required for purchase.
