Question

There are 27 students in a class. There are 5 less girls than boys. Let x = the number of boys and y = the number of girls. How many boys and girls are in the class?

Answer 1

Explanation:

x + y = 27

We know that there are 5 less girls that boys, so:

x + (x-5) = 27

x + x - 5 = 27

Solve for x:

2x - 5 = 27

2x = 32

x = 16 boys

y = 11 girls
