| ( | X | − | 5000 | − | 1023 | ) | × | 3 100 | = | X | − | 129611 25 | − | 1023 |
| 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 | − | 129611 25 | − | 1023 |
| 方程右边 = | X | − | 155186 25 |
3 100 | X | − | 18069 100 | = | X | − | 155186 25 |
3 100 | X | − | X | = | - | 155186 25 | + | 18069 100 |
| - | 97 100 | X | = | - | 155186 25 | + | 18069 100 |
| - | 97 100 | X | = | - | 24107 4 |
24107 4 | = | 97 100 | X |
97 100 | X | = | 24107 4 |
| X | = | 24107 4 | ÷ | 97 100 |
| = | 24107 4 | × | 100 97 |
| = | 24107 | × | 25 97 |
| X | = | 602675 97 |
| X | = | 6213.14433 |
