On Monday the attendance in a class was 24. There were 6 more girls than boys. How many boys were present?

Answer 1

Let x = # of boys

Let x+6 = # of girls

# of girls + # of boys = Total number in the class

(x+6) + x = 24

Now need to solve.

Combine like terms

2x + 6 = 24

Subtract 6 from both sides and simplify

2x + 6 - 6 = 24 - 6

2x = 18

Divide both sides by 2 and simplify

2x/2 = 18/2

x = 9

The number of boys in class is 9
