6-5/(v+1)=-6/(v-3)

解答

6 - \frac{5}{v + 1} = - \frac{6}{v - 3}

解答

v = \frac{3}{2}, v = \frac{1}{3}

+1

十进制

v = 1.5, v = 0.33333 \dots

求解步骤

6 - \frac{5}{v + 1} = - \frac{6}{v - 3}

乘以最小公倍数

6 (v + 1) (v - 3) - 5 (v - 3) = - 6 (v + 1)

解

6 (v + 1) (v - 3) - 5 (v - 3) = - 6 (v + 1) : v = \frac{3}{2}, v = \frac{1}{3}

v = \frac{3}{2}, v = \frac{1}{3}

验证解

找到无定义的点（奇点）:

v = - 1, v = 3

将不在定义域的点与解相综合:

v = \frac{3}{2}, v = \frac{1}{3}

流行的例子

\frac{6}{x} - \frac{1}{1 - x} = 0

2/(3w)+7/(5w)=1

\frac{2}{3 w} + \frac{7}{5 w} = 1

\frac{18}{d} = 3

\frac{4}{x} - 5 = \frac{6}{9}

solvefor a,(5+b)/(1-a)=3b

so l v e f or a, \frac{5 + b}{1 - a} = 3 b
