| ( | 415 | − | X | ) | ÷ | ( | 415 | ( | X | − | 1 | ) | X | ) | = | 29 62500 |
| Multiply both sides of the equation by: | ( | 415 | ( | X | − | 1 | ) | X | ) |
| ( | 415 | − | X | ) | = | 29 62500 | ( | 415 | ( | X | − | 1 | ) | X | ) |
| 415 | − | X | = | 29 62500 | ( | 415 | ( | X | − | 1 | ) | X | ) |
| 415 | − | X | = | 29 62500 | × | 415 | ( | X | − | 1 | ) | X |
| 415 | − | X | = | 2407 12500 | ( | X | − | 1 | ) | X |
| 415 | − | X | = | 2407 12500 | X | X | − | 2407 12500 | × | 1 | X |
| 415 | − | X | = | 2407 12500 | X | X | − | 2407 12500 | X |
