the numbers of boys in class

Answer:

number of girls = 7 + 8 = 15

The uknown in the class are the  number of  boys

Step-by-step explanation:

number of students = 23

let number of boys = y

number of girls = 7 + y

number of girls can be computed as

number of girls = students - y

number of girls = 23 - y

7 + y = 23 -y

-16 = - 2y

y = 8

number of boys = 8

number of girls = 7 + 8 = 15

The number of teacher is the unknown
