(-3)/(8r+41)=-22

解答

\frac{- 3}{8 r + 41} = - 22

解答

r = - \frac{899}{176}

+1

十进制

r = - 5.10795 \dots

求解步骤

\frac{- 3}{8 r + 41} = - 22

化简

\frac{- 3}{8 r + 41} : - \frac{3}{8 r + 41}

- \frac{3}{8 r + 41} = - 22

在两边乘以

8 r + 41

- 3 = - 22 (8 r + 41)

交换两边

- 22 (8 r + 41) = - 3

两边除以

- 22

8 r + 41 = \frac{3}{22}

将

41

到右边

8 r = - \frac{899}{22}

两边除以

8

r = - \frac{899}{176}

验证解

找到无定义的点（奇点）:

r = - \frac{41}{8}

将不在定义域的点与解相综合:

r = - \frac{899}{176}

流行的例子

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

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

1/18 = 5/(-4(x-1))

\frac{1}{18} = \frac{5}{- 4 ( x - 1 )}

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

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

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

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

\frac{x}{3} = \frac{12}{x}
