10(1-x/(10))-(10-x)-1/100 (10-x)=0.05

解答

10 (1 - \frac{x}{10}) - (10 - x) - \frac{1}{100} (10 - x) = 0.05

解答

x = 15

求解步骤

10 (1 - \frac{x}{10}) - (10 - x) - \frac{1}{100} (10 - x) = 0.05

展开

10 (1 - \frac{x}{10}) - (10 - x) - \frac{1}{100} (10 - x) : - \frac{1}{10} + \frac{1}{100} x

- \frac{1}{10} + \frac{1}{100} x = 0.05

在两边乘以

100

- 10 + x = 5

将

10

到右边

x = 15

流行的例子

- x = 3 - (3 x + 5)

2 [x + 3 (x + 1)] = 5 x

\frac{2 k}{5} + \frac{k}{2} = 18

3*(x-2)-(x+1)=5

3 \cdot (x - 2) - (x + 1) = 5

\frac{3}{4} + \frac{1}{2} = x - \frac{2}{7}
