| ( | X | − | 5000 | − | 1023 | ) | × | 3 100 | = | X | − | 1023 | − | 32961 4 |
| 方程左边 = | X | × | 3 100 | − | 5000 | × | 3 100 | − | 1023 | × | 3 100 |
| = | X | × | 3 100 | − | 150 | − | 3069 100 |
| = | 3 100 | X | − | 18069 100 |
3 100 | X | − | 18069 100 | = | X | − | 1023 | − | 32961 4 |
| 方程右边 = | X | − | 37053 4 |
3 100 | X | − | 18069 100 | = | X | − | 37053 4 |
3 100 | X | − | X | = | - | 37053 4 | + | 18069 100 |
| - | 97 100 | X | = | - | 37053 4 | + | 18069 100 |
| - | 97 100 | X | = | - | 227064 25 |
227064 25 | = | 97 100 | X |
97 100 | X | = | 227064 25 |
| X | = | 227064 25 | ÷ | 97 100 |
| = | 227064 25 | × | 100 97 |
| = | 227064 | × | 4 97 |
| X | = | 908256 97 |
| X | = | 9363.463918 |
