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?

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

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

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

Let boys=x and girls=x+16:-
boys + girls =218
x + (x+16 =218
2x + 16 =218
x = (218-16)/2
Hence boys =101 and girls =101+16
Hope this helps
