4. Five pencils and 2 erasers cost 95 cents. Three pencils and 4 erasers cost 85 cents. If x is the cost of a pencil and y is the cost of an eraser, then which of the following systems of equations can be used to find the cost of a pencil?

- x û y = 2

8x + 6y = 180 - x + y = 14

8x + 6y = 180 - 5x + 4y = 95

3x + 2y = 85 - 5x + 2y = 95

3x + 4y = 85 - None of these
