Question

A senior class at Smith High School has 84 students.

The number of boys in the class is 4 more than the number of girls.
How many boys and girls are there in the class, respectively?​

Answer 1

Answer: 44 boys and 40 girls

Explanation:

x = number of girls

x + 4 = number of boys

x + x + 4 = 84

2x + 4 = 84

2x = 80

x = 40

84 - 40 = 44
