Question

In a class, 45 students are taking the SAT exam.The number of boys is 9 more than the number of girls.How many girls and boys are in the classroom?
Write a system of equations and solve using any method.

Answer 1

The equation would be
g + (g + 9) = 45
2g + 9 = 45
- 9
2g = 36
÷ 2
g = 18
18 + 9 = 27
Girls: 18
Boys: 27
