Question

The number of boys in 7y is 3 more than the number of girls. If there are 19 students in 7y, how many are girls and how many are boys?

Answer 1

There are 8 girls and 11 boys

Explanation:

7y= 19

19-3=16

16÷2= 8

8+3= 11

8 girls and 11 boys

boys have 3 more so subtract before u calculate then divide by 2 since there are 2 groups and then add the excess 3 to the boys.
