SUMMARY
The discussion centers on the differential equation dy/dx + y = x, where x is identified as the independent variable and y as the dependent variable. Participants clarify that in such equations, y is always a function of x due to the nature of the relationship defined by the differential equation. This understanding is typically derived from the context of the problem, where x or t is conventionally used as the independent variable. The notation dy(x)/dx reinforces this relationship, indicating that y is explicitly dependent on x.
