| ( | 1126 | − | X | ) | ÷ | X | = | - | 78 625 |
| Multiply both sides of the equation by: | X |
| ( | 1126 | − | X | ) | = | - | 78 625 | X |
| 1126 | − | X | = | - | 78 625 | X |
| - | X | + | 78 625 | X | = | - | 1126 |
| - | 547 625 | X | = | - | 1126 |
| 1126 | = | 547 625 | X |
547 625 | X | = | 1126 |
| X | = | 1126 | ÷ | 547 625 |
| = | 1126 | × | 625 547 |
| X | = | 703750 547 |
| X | = | 1286.563071 |
