Say there are x students of which y like apples
y:x-y = 5:8
You arent making any sense. whats the answer then?
it might be easier to look at it in fraction form
y/(x-y) = 5/8
(y+5)/(x-y) = 5/6
y is the students who like apples, x is the total num of students
x-y students like oranges
you have to solve the system of proportions for x and y
