The number of boys in the classroom is three more than the number of girls if there are 19 students how many are boys and how many are girls

11 boys 8 girls

Step-by-step explanation:

There are 19 total students.

There are 3 more boys than girls

girls + 3 = boys (because there are three more boys)

boys + girls = 19

You can substitute g + 3 for b so:

2 girls + 3 = 19

19 - 3 = 16

16/2 = girls

8 = girls

Once you find g just subtract the amount of girls from 19 to get the amount of boys.

19 kids - 8 girls = 11 boys
