| X | ( | 123 | ÷ | X | ) | + | 255 | ( | 1 | − | ( | 123 | ÷ | X | ) | ) | = | 41 |
| 1 | × | 123 | ÷ | 1 | + | 255 | ( | 1 | − | ( | 123 | ÷ | X | ) | ) | = | 41 |
| 123 | + | 255 | ( | 1 | − | ( | 123 | ÷ | X | ) | ) | = | 41 |
| 123 | + | 255 | × | 1 | − | 255 | ( | 123 | ÷ | X | ) | = | 41 |
| 123 | + | 255 | − | 255 | ( | 123 | ÷ | X | ) | = | 41 |
| 378 | − | 255 | ( | 123 | ÷ | X | ) | = | 41 |
| 378 | − | 255 | × | 123 | ÷ | X | = | 41 |
| 378 | − | 31365 | ÷ | X | = | 41 |
| Multiply both sides of the equation by: | X |
| 378 | X | − | 31365 | = | 41 | X |
| 378 | X | − | 41 | X | = | 31365 |
| 337 | X | = | 31365 |
| X | = | 31365 | ÷ | 337 |
| = | 31365 | × | 1 337 |
| X | = | 31365 337 |
| X | = | 93.071217 |
