| 29980000 | ÷ | ( | 1 | − | X | ) | × | X | = | 3963900 |
| Multiply both sides of the equation by: | ( | 1 | − | X | ) |
| 29980000 | X | = | 3963900 | ( | 1 | − | X | ) |
| 29980000 | X | = | 3963900 | × | 1 | − | 3963900 | X |
| 29980000 | X | = | 3963900 | − | 3963900 | X |
| 29980000 | X | + | 3963900 | X | = | 3963900 |
| 33943900 | X | = | 3963900 |
| X | = | 3963900 | ÷ | 33943900 |
| = | 3963900 | × | 1 33943900 |
| = | 39639 | × | 1 339439 |
| X | = | 39639 339439 |
| X | = | 0.116778 |
