    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
