Let us consider the total number of boys to be x and that of girls to be y.
First information: Total number of students is 656.
So x+y = 656
Second information: The number of girls is 86 more than that of boys.
So y = x+86
or, y-x = 86
So, our equations are:
x+y=656
y-x=86
Your graph should look something like the one I have attached.
So, the number of boys is 285 and the number of girls is 371.
