| ( | x | − | 10391 5 | ) | ÷ | x | = | 99 10000 |
| Multiply both sides of the equation by: | x |
| ( | x | − | 10391 5 | ) | = | 99 10000 | x |
| x | − | 10391 5 | = | 99 10000 | x |
| x | − | 99 10000 | x | = | 10391 5 |
9901 10000 | x | = | 10391 5 |
| x | = | 10391 5 | ÷ | 9901 10000 |
| = | 10391 5 | × | 10000 9901 |
| = | 10391 | × | 2000 9901 |
| x | = | 20782000 9901 |
| x | = | 2098.979901 |
