<span>y=mx+c
General equation
m is the slope
c is the intercept
So, when x axis is zero, the value in y axis will be equal to c.

if the number of boys is x ,then the number of girls is x+7,so 2x+7=35,we can know x=9,so the number of boys is 9,and girls are 16
4.5(8 - x) + 36 = 102 - 2.5(3x + 24)
36 - 4.5x + 36 = 102 - 7.5x - 60
72 - 4.5x = 42 - 7.5x
-4.5x + 7.5x = 42 - 72
3x = - 30
x = -30/3
x = -10 <===
Hope this helps!
