Question

In a class there are 48 students.the number of girls is 3 times their boys . how many boys and girls are there in the class??​please help!

Answer 1

12 boys, 36 girls

Explanation:

We can use systems of equations to solve this using substitution.

Let b = # of boys in the class

Let g = # of girls in the class

b + g = 48

g=3b

b+(3b)=48

4b=48

b=12

12*3=36

Check:

36+12=48
