| 190 | ÷ | 110 | = | X | ÷ | ( | 1 | − | X | ) |
| Multiply both sides of the equation by: | ( | 1 | − | X | ) |
| 190 | ÷ | 110 | × | ( | 1 | − | X | ) | = | X |
| 190 | ÷ | 110 | × | 1 | − | 190 | ÷ | 110 | × | X | = | X |
19 11 | − | 19 11 | X | = | X |
| - | 19 11 | X | − | X | = | - | 19 11 |
| - | 30 11 | X | = | - | 19 11 |
19 11 | = | 30 11 | X |
30 11 | X | = | 19 11 |
| X | = | 19 11 | ÷ | 30 11 |
| = | 19 11 | × | 11 30 |
| = | 19 | × | 1 30 |
| X | = | 19 30 |
| X | = | 0.633333 |
