(x-8}{x-3}=\frac{-4)/x

解答

\frac{x - 8}{x - 3} = \frac{- 4}{x}

x = 6, x = - 2

求解步骤

\frac{x - 8}{x - 3} = \frac{- 4}{x}

使用分式交叉相乘

(x - 8) x = - (x - 3) \cdot 4

解

(x - 8) x = - (x - 3) \cdot 4 : x = 6, x = - 2

x = 6, x = - 2

验证解

找到无定义的点（奇点）:

x = 3, x = 0

将不在定义域的点与解相综合:

x = 6, x = - 2

so l v e f or a, 5 q = \frac{f}{a} + g

\frac{3}{x + 6} = \frac{6}{x - 1}

\frac{( - 6 - 6 )}{x} = - 4

0 = \frac{2}{n - 2} - \frac{6}{n + 1}

\frac{3}{x + 2} = \frac{6}{x - 1}
