| ( | 10219 | − | x | ) | ÷ | x | = | - | 22 500 |
| Multiply both sides of the equation by: | x |
| ( | 10219 | − | x | ) | = | - | 22 500 | x |
| 10219 | − | x | = | - | 22 500 | x |
| - | x | + | 22 500 | x | = | - | 10219 |
| - | 239 250 | x | = | - | 10219 |
| 10219 | = | 239 250 | x |
239 250 | x | = | 10219 |
| x | = | 10219 | ÷ | 239 250 |
| = | 10219 | × | 250 239 |
| x | = | 2554750 239 |
