x+2=(6x-3)/x

解答

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

解答

x = 3, x = 1

求解步骤

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

在两边乘以

x

x^{2} + 2 x = 6 x - 3

解

x^{2} + 2 x = 6 x - 3 : x = 3, x = 1

x = 3, x = 1

验证解

找到无定义的点（奇点）:

x = 0

将不在定义域的点与解相综合:

x = 3, x = 1

流行的例子

4/(x^2-4)= 1/(x-2)

\frac{4}{x ^{2} - 4} = \frac{1}{x - 2}

((6000)/x)-100-50x=250

(\frac{6000}{x}) - 100 - 50 x = 250

\frac{1}{x ^{2}} + \frac{5}{x} = 7

(10)/x+3/(x-6)=1

\frac{10}{x} + \frac{3}{x - 6} = 1

1/(4x)-1/4 = 1/2

\frac{1}{4 x} - \frac{1}{4} = \frac{1}{2}
