(1+1)/(2(4x-6))=-2

解答

\frac{1 + 1}{2 ( 4 x - 6 )} = - 2

解答

x = \frac{11}{8}

+1

十进制

x = 1.375

求解步骤

\frac{1 + 1}{2 ( 4 x - 6 )} = - 2

化简

\frac{1 + 1}{2 ( 4 x - 6 )} : \frac{1}{4 x - 6}

\frac{1}{4 x - 6} = - 2

在两边乘以

4 x - 6

1 = - 2 (4 x - 6)

交换两边

- 2 (4 x - 6) = 1

两边除以

- 2

4 x - 6 = - \frac{1}{2}

将

6

到右边

4 x = \frac{11}{2}

两边除以

4

x = \frac{11}{8}

验证解

找到无定义的点（奇点）:

x = \frac{3}{2}

将不在定义域的点与解相综合:

x = \frac{11}{8}

流行的例子

solvefor x,1=(y-x)/(y+x)

so l v e f or x, 1 = \frac{y - x}{y + x}

\frac{3}{5} = \frac{30}{x}

(3+1)/(x+1)=(4x)/(x+1)

\frac{3 + 1}{x + 1} = \frac{4 x}{x + 1}

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

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

(x-6}{3x}+8=\frac{x+5)/x

\frac{x - 6}{3 x} + 8 = \frac{x + 5}{x}
