\begin{equation*}
\begin{split}
1 + \frac{3}{x + 2} + \frac{2}{x + 3} & = \frac{3}{(x + 2)(x + 3)} \quad {\color {blue} \times (x + 2)(x + 3)} \\\\
(x + 2)(x + 3) + 3(x + 3) + 2(x + 2) & = 3 \\\\
x^2 + 5x + 6 + 3x + 9 + 2x + 4 - 3 & = 0 \\\\
x^2 + 10x + 16 & = 0 \\\\
(x + 8)(x + 2) & = 0 \\\\
x = -8 \text{ atau } x & = -2
\end{split}
\end{equation*}

Karena p > q, maka p = −2 dan q = −8, dan 3p − q = 2
