1 1/2-x= 1/10

解答

1 \frac{1}{2} - x = \frac{1}{10}

解答

x = 1 \frac{2}{5}

+1

十进制

x = 1.4

求解步骤

1 \frac{1}{2} - x = \frac{1}{10}

将带分数转换为假分式:

1 \frac{1}{2} = \frac{3}{2}

\frac{3}{2} - x = \frac{1}{10}

将

\frac{3}{2}

到右边

- x = - \frac{7}{5}

两边除以

- 1

x = \frac{7}{5}

将假分式转换为带分数:

\frac{7}{5} = 1 \frac{2}{5}

x = 1 \frac{2}{5}

(x-1)/2 =(x-3)/4-(x-4)/5

\frac{x - 1}{2} = \frac{x - 3}{4} - \frac{x - 4}{5}

30 = \frac{1}{2} (x - 50)

4(3x-2)=2[x-5(x-6)]

4 (3 x - 2) = 2 [x - 5 (x - 6)]

2 1/2 x-1 5/8 =2 3/4

2 \frac{1}{2} x - 1 \frac{5}{8} = 2 \frac{3}{4}
