1-x=(2.47x)/(1+(1.47x))

解答

1 - x = \frac{2.47 x}{1 + ( 1.47 x )}

解答

x = - \frac{2 + 9.88}{2.94}, x = \frac{9.88 - 2}{2.94}

+1

十进制

x = - 1.74940 \dots, x = 0.38885 \dots

求解步骤

1 - x = \frac{2.47 x}{1 + ( 1.47 x )}

化简

\frac{2.47 x}{1 + ( 1.47 x )} : \frac{2.47 x}{1 + 1.47 x}

1 - x = \frac{2.47 x}{1 + 1.47 x}

在两边乘以

1 + 1.47 x

1 + 1.47 x - x (1 + 1.47 x) = 2.47 x

解

1 + 1.47 x - x (1 + 1.47 x) = 2.47 x : x = - \frac{2 + 9.88}{2.94}, x = \frac{9.88 - 2}{2.94}

x = - \frac{2 + 9.88}{2.94}, x = \frac{9.88 - 2}{2.94}

验证解

找到无定义的点（奇点）:

x = - \frac{100}{147}

将不在定义域的点与解相综合:

x = - \frac{2 + 9.88}{2.94}, x = \frac{9.88 - 2}{2.94}

流行的例子

(370)/(x+6)=3.8+0.2x

\frac{370}{x + 6} = 3.8 + 0.2 x

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

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

solvefor r,θ=(18-2r)/r

so l v e f or r, θ = \frac{18 - 2 r}{r}

(x^2-7x-18)/(x+2)=x-9

\frac{x ^{2} - 7 x - 18}{x + 2} = x - 9

\frac{5}{x} + 1 = 0
