To find :
Formulate the problem algebraically and solve it graphically.
Solution :
5x+3y=35
2x+4y=28
5x+3y=35x2
2x+4y=28x5
10x+6y=70
10x+20y=140
y=5
x=4

Answer:
5x+3y = 35
2x+4y =28
on subtracting
3x-y =7
3x = 7+y
if x = 4 , then
7+y = 12
y = 5
so x = 4 means cost of each apple
and y = 5 means cost of each orange
