1/(x-2)+5=(16)/(x-2)

解答

\frac{1}{x - 2} + 5 = \frac{16}{x - 2}

解答

x = 5

求解步骤

\frac{1}{x - 2} + 5 = \frac{16}{x - 2}

在两边乘以

x - 2

1 + 5 (x - 2) = 16

将

1

到右边

5 (x - 2) = 15

两边除以

5

x - 2 = 3

将

2

到右边

x = 5

验证解

找到无定义的点（奇点）:

x = 2

将不在定义域的点与解相综合:

x = 5

流行的例子

solvefor t,m-5n= f/t

so l v e f or t, m - 5 n = \frac{f}{t}

\frac{4}{z} = \frac{12}{5}

A = \frac{x}{x} -, 2 < x < 4

5/(x-3)+2= 9/(x-3)

\frac{5}{x - 3} + 2 = \frac{9}{x - 3}

1-3/x =-2/(x^2)

1 - \frac{3}{x} = - \frac{2}{x ^{2}}
