1. How does the author determine what the first equation should be?

The first equation is the equation formed out of the first information in the problem. If the variables in the question are taken as x and y, usually the first equation will be x + y = k, where k is the sum of x and y as given in the question. This step is called "Total value" step and the resulting equation is called "Total Value" equation.

2. What about the second equation?

The second equation is the equation formed out ...
