Answer

La solución general de la ecuación diferencial \( ( y + e^{x} )\, dx + ( x + e^{y} )\, dy = 0 \) es: \[ xy + e^{x} + e^{y} = C, \] donde \(C\) es una constante arbitraria.

This differential equation is an example of an exact equation, which means there exists a function \( F(x, y) \) such that \( \frac{\partial F}{\partial x} = y + e^x \) and \( \frac{\partial F}{\partial y} = x + e^y \). To solve it, you can integrate both expressions to find \( F(x, y) \) and then set \( F(x, y) = C \) for some constant \( C \). Doing so will give you the implicit solution to the equation. When approaching such equations, a common mistake is overlooking the exactness condition. Before proceeding with integrating, always verify if \( \frac{\partial M}{\partial y} = \frac{\partial N}{\partial x} \) holds true, where \( M \) and \( N \) are the coefficients of \( dx \) and \( dy \) respectively. If they don’t match, the equation may require an integrating factor!
