2.5= x/((0.5667-x)(1-x))

解答

2.5 = \frac{x}{( 0.5667 - x ) ( 1 - x )}

解答

x = \frac{4.91675 + 10.00693 \dots}{5}, x = \frac{4.91675 - 10.00693 \dots}{5}

+1

十进制

x = 1.61602 \dots, x = 0.35067 \dots

求解步骤

2.5 = \frac{x}{( 0.5667 - x ) ( 1 - x )}

在两边乘以

(0.5667 - x) (1 - x)

2.5 (0.5667 - x) (1 - x) = x

解

2.5 (0.5667 - x) (1 - x) = x : x = \frac{4.91675 + 10.00693 \dots}{5}, x = \frac{4.91675 - 10.00693 \dots}{5}

x = \frac{4.91675 + 10.00693 \dots}{5}, x = \frac{4.91675 - 10.00693 \dots}{5}

验证解

找到无定义的点（奇点）:

x = 0.5667, x = 1

将不在定义域的点与解相综合:

x = \frac{4.91675 + 10.00693 \dots}{5}, x = \frac{4.91675 - 10.00693 \dots}{5}

流行的例子

solvefor x, c/x =d+r

so l v e f or x, \frac{c}{x} = d + r

j (x) = \frac{5}{x - 2}

0.22=1-((115000)/x)

0.22 = 1 - (\frac{115000}{x})

solvefor y,-(16x)/y =1

so l v e f or y, - \frac{16 x}{y} = 1

x/(5-x)= 3/(20-4x)

\frac{x}{5 - x} = \frac{3}{20 - 4 x}
