For flexibility in course contents, advanced or optional topics such as extreme-value distributions, regression and linear models, and reliability and survival distributions are included. The rational is that we have $W=X+Y$ and a general transformation of pdf between coordinate systems when we have a bijection between $\langle X,Y\rangle$ and $\langle W, V\rangle$. \end{align} Next we will get the marginal density of $W$ by integrating \begin{align} f_W(w) & = \int_{0}^{w} 4e^{-2w}dv \\ & = 4e^{-2w}[v]_{0}^{w} \\ & = 4we^{-2w}. Lee J. Bain and Max Engelhardt focus on the mathematical development of the subject, with examples and exercises oriented toward applications.

Special probability distributions are placed separately in Chapter 3. I guess if the goal is to get the distribution of $W := X + Y$, then introducing some "artificial" transformation $V$ to get a joint density for $W$ and $V$, then later integrating out all occurrences of that $V$ to get $F_W$ alone will work just fine.

My question comes after the solution. For this particular problem, the solution is to use this with $g_{\small x}(w,v)=v$, and $g_{\small y}(w,v)=w-v$.
