| ( | 1569 | − | X | ) | ÷ | X | = | - | 1807 100000 |
| Multiply both sides of the equation by: | X |
| ( | 1569 | − | X | ) | = | - | 1807 100000 | X |
| 1569 | − | X | = | - | 1807 100000 | X |
| - | X | + | 1807 100000 | X | = | - | 1569 |
| - | 98193 100000 | X | = | - | 1569 |
| 1569 | = | 98193 100000 | X |
98193 100000 | X | = | 1569 |
| X | = | 1569 | ÷ | 98193 100000 |
| = | 1569 | × | 100000 98193 |
| = | 523 | × | 100000 32731 |
| X | = | 52300000 32731 |
