Let c = number of children in the room.
Let p = the number of parents in the room.
There are 9 more children than parents in the room. Therefore
c = p +9 (1)
There are 25 people in the room. Therefore
c + p = 25 (2)
Answer:
The expression for the number of parents is
p = 25 c

Note:
We can determine the number of children and parents.
Substitute (1) into (2).
p + 9 + p = 25
2p + 9 = 25
2p = 25  9 = 16
p = 16/2 = 8
c = p + 9 = 8 + 9 = 17
Number of children = 17
Number of parents = 8
