A fruit company packages its fruit into two types of boxes: large and small. This morning, the company made two deliveries. The table below shows the number of boxes in each delivery and the total weight (in kilograms).

Let x be the weight (in kilograms) of each large box.
Let y be the weight (in kilograms) of each small box.

Which of the following systems of equations could be used to find the weight (in kilograms) of each type of box?

• 8x + 3y = 142
  2x + 5y = 61

• 8x + 2y = 142
  3x + 5y = 61

• 3x + 8y = 142
  5x + 2y = 61

• 8x + 5y = 142
  2x + 3y = 61
