0.02572= 1/((19.1+1.5+x))

解答

0.02572 = \frac{1}{( 19.1 + 1.5 + x )}

解答

x = \frac{1}{0.02572} - 20.6

+1

十进制

x = 18.28024 \dots

求解步骤

0.02572 = \frac{1}{( 19.1 + 1.5 + x )}

化简

\frac{1}{19.1 + 1.5 + x} : \frac{1}{x + 20.6}

0.02572 = \frac{1}{x + 20.6}

在两边乘以

x + 20.6

0.02572 (x + 20.6) = 1

两边除以

0.02572

x + 20.6 = \frac{1}{0.02572}

将

20.6

到右边

x = \frac{1}{0.02572} - 20.6

验证解

找到无定义的点（奇点）:

x = - 20.6

将不在定义域的点与解相综合:

x = \frac{1}{0.02572} - 20.6

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

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

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

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

0.24 = \frac{21}{x}

((x)(x))/((0.5-x))=8.3

\frac{( x ) ( x )}{( 0.5 - x )} = 8.3

3/(4x-2)= 5/(7x+3)

\frac{3}{4 x - 2} = \frac{5}{7 x + 3}
