How do you solve this equation;
There are 128 7th graders at Mark's school, if there are 16 more girls than boys, how many 7th grade boys are there?

  • Math -

    first you subtract 16 from the number of all students , then divide that number by two and you will get your answer .

  • Math -

    128=x+16
    128= number of total students.
    X= the number of boys
    so, 16+X because there are 16 more girls than boys...
    so subract 16 from 128 which equals 112
    so the number of boys is 112 and the number of girls is 112+16

  • Math -

    Subtract 16 from the number of all students. 128 - 16 = 112. Divide 112 by 2 = 56. There are 56 BOYS and 56 + 16 = 72 GIRLS

  • Math -

    Let boys=x and girls=x+16:-

    boys + girls =218
    x + (x+16 =218
    2x + 16 =218
    x = (218-16)/2
    = 101
    Hence boys =101 and girls =101+16

    Hope this helps
