Suppose that a farmer cultivates two crops: corn (x) and soy (y). For this, the farmer has to use both fertilizer and pesticide. One unit of corn requires 6 units of fertilizer and 3 units of pesticide. Similarly, 1 unit of soy requires 5 units of fertilizer and 4 units of pesticide, respectively. The farmer has 49 units of fertilizer and 32 units of pesticides for both crops. Find the quantities of the two crops, x and y that will use up all fertilizer and the pesticides.
