x/((x+10))=0.94

解答

\frac{x}{( x + 10 )} = 0.94

解答

x = \frac{470}{3}

+1

十进制

x = 156.66666 \dots

求解步骤

\frac{x}{( x + 10 )} = 0.94

化简

\frac{x}{( x + 10 )} : \frac{x}{x + 10}

\frac{x}{x + 10} = 0.94

在两边乘以

x + 10

x = 0.94 (x + 10)

在两边乘以

100

x \cdot 100 = 94 (x + 10)

展开

94 (x + 10) : 94 x + 940

x \cdot 100 = 94 x + 940

将

94 x

para o lado esquerdo

6 x = 940

两边除以

6

x = \frac{470}{3}

验证解

找到无定义的点（奇点）:

x = - 10

将不在定义域的点与解相综合:

x = \frac{470}{3}

1/(3x^2(x-3)+x^2)=-9

\frac{1}{3 x ^{2} ( x - 3 ) + x ^{2}} = - 9

d/((x+10))-d/((x-10))=4

\frac{d}{( x + 10 )} - \frac{d}{( x - 10 )} = 4

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

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

(11)/(7x+1)= 41/2

\frac{11}{7 x + 1} = \frac{41}{2}

x/(4(2x-3))=6x+2

\frac{x}{4 ( 2 x - 3 )} = 6 x + 2
