How many boys are in a class of thirty-five student if the girls outnumber boys by five

15 Boys because 35-5 is 30 then divide 30 by 2 to get 15

To solve:

Set an equation:
Boys=x
Girls=x+5

x+x+5=35
2x+5=35

Subtract 5 from both sides

2x=30

Divide both sides by 2

x=15

Answers: There are 15 boys and 20 girls in the class.
