Answer:

$7; Cost of a box of apples (x)

$13; Cost of a box of oranges (y)

Step-by-step explanation:

Matt: 3x + 14y = 203           3(-y + 20) + 14y = 203          3x + 14(13) = 203

Ming: 11x + 11y = 220         -3y + 60 + 14y = 203             3x + 182 = 203

         11x = -11                           11y = 143                               3x = 21

           x = -y + 20                      y = 13                                  x = 7
