2 5 | x | + | 9 10 | ÷ | 1 2 | − | 3 100 | + | 1 50 | x | ÷ | 3 100 | = | x | − | 5 | ÷ | 2 |
| 方程左边 = | 2 5 | x | + | 9 5 | − | 3 100 | + | 2 3 | x |
| = | 16 15 | x | + | 177 100 |
16 15 | x | + | 177 100 | = | x | − | 5 | ÷ | 2 |
| 方程右边 = | x | − | 5 2 |
16 15 | x | + | 177 100 | = | x | − | 5 2 |
16 15 | x | − | x | = | - | 5 2 | − | 177 100 |
1 15 | x | = | - | 5 2 | − | 177 100 |
1 15 | x | = | - | 427 100 |
| x | = | - | 427 100 | ÷ | 1 15 |
| = | - | 427 100 | × | 15 |
| = | - | 427 20 | × | 3 |
| x | = | - | 1281 20 |
| x | = | - 64.05 |
