How do you solve this equation;

Question

There are 128 7th graders at Mark's school, if there are 16 more girls than boys, how many 7th grade boys are there?

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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
