There are 35 people in a room.

Question

There are seven more males than females in the room. How many males are there? How many females are there? 

Answer 1

Let number of males = x +7

Let number of females = x

 

Set up equation:

 

x + x + 7 = 35

2x + 7 = 35

2x = 28

  x = 14

 

There are 14 females.

Answer 2

f = number of females

f + 7 = number of males

 

f + f + 7 = 35

2f + 7 = 35

2f = 28

f = 14

 

There fore 14 females and 21 males in the room.
