2 5 | + | 9 10 | ÷ | 1 2 | − | 3 100 | + | 1 50 | x | ÷ | 3 100 | = | x | − | 5 | ÷ | 2 |
| 方程左边 = | 2 5 | + | 9 5 | − | 3 100 | + | 2 3 | x |
| = | 217 100 | + | 2 3 | x |
217 100 | + | 2 3 | x | = | x | − | 5 | ÷ | 2 |
| 方程右边 = | x | − | 5 2 |
217 100 | + | 2 3 | x | = | x | − | 5 2 |
2 3 | x | − | x | = | - | 5 2 | − | 217 100 |
| - | 1 3 | x | = | - | 5 2 | − | 217 100 |
| - | 1 3 | x | = | - | 467 100 |
467 100 | = | 1 3 | x |
1 3 | x | = | 467 100 |
| x | = | 467 100 | ÷ | 1 3 |
| = | 467 100 | × | 3 |
| x | = | 1401 100 |
| x | = | 14.01 |
