| ( | 5000 | × | 12 | × | 9 10 | − | 70 100 | × | 130 | X | × | 32 500 | ) | = | 0 |
| Left side of the equation = | 5000 | × | 12 | × | 9 10 | − | 70 100 | × | 130 | X | × | 32 500 |
| = | 54000 | − | 728 125 | X |
| 54000 | − | 728 125 | X | = | 0 |
| - | 728 125 | X | = | 0 | − | 54000 |
| - | 728 125 | X | = | - | 54000 |
| 54000 | = | 728 125 | X |
728 125 | X | = | 54000 |
| X | = | 54000 | ÷ | 728 125 |
| = | 54000 | × | 125 728 |
| = | 6750 | × | 125 91 |
| X | = | 843750 91 |
| X | = | 9271.978022 |
