$$\left. \begin{array} { l } { 20 n d 2 m = -2 n }\\ { o = a m - 4 n }\\ { p = o }\\ { q = p }\\ { r = q }\\ { \text{Solve for } s \text{ where} } \\ { s = r } \end{array} \right.$$

解 n、d_2、m、o、a、p、q、r、s

$$r=o\text{, }s=o\text{, }n=\frac{am-o}{4}\text{, }d_{2}\neq 0\text{, }m=-\frac{1}{10d_{2}}\text{, }o\in \mathrm{R}\text{, }a\in \mathrm{R}\text{, }p=o\text{, }q=o$$

$$r=0\text{, }s=0\text{, }n=0\text{, }d_{2}\in \mathrm{R}\text{, }m\in \mathrm{R}\text{, }o=0\text{, }a=0\text{, }p=0\text{, }q=0$$

$$r=o\text{, }s=o\text{, }n=\frac{am-o}{4}\text{, }d_{2}\in \mathrm{R}\text{, }m=\frac{o}{a}\text{, }o\in \mathrm{R}\text{, }a\neq 0\text{, }p=o\text{, }q=o$$
