3 10 | x | + | 1 2 | ÷ | 1 2 | = | 2 | x | − | 1 | ÷ | 3 |
| 方程左边 = | 3 10 | x | + | 1 |
3 10 | x | + | 1 | = | 2 | x | − | 1 | ÷ | 3 |
| 方程右边 = | 2 | x | − | 1 3 |
3 10 | x | + | 1 | = | 2 | x | − | 1 3 |
3 10 | x | − | 2 | x | = | - | 1 3 | − | 1 |
| - | 17 10 | x | = | - | 1 3 | − | 1 |
| - | 17 10 | x | = | - | 4 3 |
4 3 | = | 17 10 | x |
17 10 | x | = | 4 3 |
| x | = | 4 3 | ÷ | 17 10 |
| = | 4 3 | × | 10 17 |
| x | = | 40 51 |
| x | = | 0.784314 |
