10-(3X+5)/6 =3 11/12-(X/2)/(4/1)

解答

10 - \frac{3 X + 5}{6} = 3 \frac{11}{12} - \frac{\frac{X}{2}}{\frac{4}{1}}

解答

X = 14

求解步骤

10 - \frac{3 X + 5}{6} = 3 \frac{11}{12} - \frac{\frac{X}{2}}{\frac{4}{1}}

将带分数转换为假分式:

3 \frac{11}{12} = \frac{47}{12}

10 - \frac{3 X + 5}{6} = \frac{47}{12} - \frac{\frac{X}{2}}{\frac{4}{1}}

\frac{\frac{X}{2}}{\frac{4}{1}} = \frac{X}{8}

10 - \frac{3 X + 5}{6} = \frac{47}{12} - \frac{X}{8}

将

\frac{X}{8}

para o lado esquerdo

\frac{- 9 X - 20}{24} + 10 = \frac{47}{12}

将

10

到右边

\frac{- 9 X - 20}{24} = - \frac{73}{12}

在两边乘以

24

- 9 X - 20 = - 146

将

20

到右边

- 9 X = - 126

两边除以

- 9

X = 14

流行的例子

(3x+1)/4-(2x-3)/2 = 1/8 (x-2)+(x+2)/3

\frac{3 x + 1}{4} - \frac{2 x - 3}{2} = \frac{1}{8} (x - 2) + \frac{x + 2}{3}

3 + 5 - x = x

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

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

\frac{x}{16} = \frac{5}{4}

x/2-3/2 =(3x)/4+1/12

\frac{x}{2} - \frac{3}{2} = \frac{3 x}{4} + \frac{1}{12}
