Example:

There are 62 children in a room. There are 8 more boys than girls in the room. How many boys are in the

room? How many girls are in the room?

Girls

Boys

6

6+8 = 14

2

2+8= 10

4

4+8=12

x

x+8

Let x be the number of girls-

Formula you want to use: x+(x+8) = 62

Solve: x + x + 8 = 62

2x+8=62

2x+8-8=62-8

2x=54

2x divided by 2 = 54 divided by 2

X=27

If there are 35 boys, then there are 27 girls. There are 62 children total and 8 more boys than

girls just as the problem stated.
