Since the value of y is needed, you do not need a full solution. You need to get a way to answer the question as quickly as possible. I would multiply the first equation times (-1), getting and I would add the second equation to that, getting --> --> So, the quantity in column B is 1, and since the quantity in column A is 2, the quantity in column A is greater.
