( | 1 5 | − | x | ÷ | 3 10 | ) | − | 1 | = | 1 10 | + | x | ÷ | 1 5 |
方程左边 = | 1 5 | − | x | ÷ | 3 10 | − | 1 |
= | - | 4 5 | − | 10 3 | x |
- | 4 5 | − | 10 3 | x | = | 1 10 | + | x | ÷ | 1 5 |
- | 10 3 | x | − | 5 | x | = | 1 10 | + | 4 5 |
- | 25 3 | x | = | 1 10 | + | 4 5 |
- | 25 3 | x | = | 9 10 |
- | 9 10 | = | 25 3 | x |
25 3 | x | = | - | 9 10 |
x | = | - | 9 10 | ÷ | 25 3 |
= | - | 9 10 | × | 3 25 |
x | = | - | 27 250 |
x | = | - 0.108 |
