Answer:
⅔∙x – ½∙y = 500
The letters x and y represent the areas of the fields. The first equation is understood simply as "adding the two areas gives a total area of 1,800 square yards." The second equation is more subtle. Since x is the area of the first field, and the first field had a yield of two-thirds of a gallon per square yard, "⅔∙x" — meaning "two-thirds times x" — represents the total amount of grain produced by the first field. Similarly "½∙y" represents the total amount of grain produced by the second field. Since the first field gave 500 more gallons of grain than the second, the difference (hence, subtraction) between the first field's grain (⅔∙x) and the second field's grain (½∙y) is (=) 500 gallons.

Of course, the power of algebra isn't in coding statements about the physical world. Computer scientist and author Mark Jason Dominus writes on his blog, The Universe of Discourse: "In the first phase you translate the problem into algebra, and then in the second phase you manipulate the symbols, almost mechanically, until the answer pops out as if by magic." While these manipulation rules derive from mathematical principles, the novelty and non-sequitur nature of "turning the crank" or "plugging and chugging" has been noticed by many students and professionals alike.
Here, we will solve this problem using techniques as they are taught today. And as a disclaimer, the reader does not need to understand each specific step to grasp the importance of this overall technique. It is my intention that the historical significance and the fact that we are able to solve the problem without any guesswork will inspire inexperienced readers to learn about these steps in greater detail. Here is the first equation again:
