After 3 hours of work a farmer has harvested 480 fruits. After 5 hours he harvested 550 fruits. Is this a proportional relationship?

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)
