Question

There are 30 students in the math class. There are 6 more boys than 1/2 the number of girls. Write a system of linear equations to represent this scenario.

Answer 1

Answer: the system of linear equations to represent this scenario are

b + g = 30

2b = g + 12

Step-by-step explanation:

Let b represent the number of boys in the class.

Let g represent the number of girls in the class.

There are 30 students in the math class. This can be expressed as

b + g = 30

There are 6 more boys than 1/2 the number of girls in the class. This can be expressed as

b = g/2 + 6

Cross multiplying by 2, the expression becomes

2b = g + 12
