| ( | 6310 | − | x | ) | ÷ | x | = | 19 100 |
| Multiply both sides of the equation by: | x |
| ( | 6310 | − | x | ) | = | 19 100 | x |
| 6310 | − | x | = | 19 100 | x |
| - | x | − | 19 100 | x | = | - | 6310 |
| - | 119 100 | x | = | - | 6310 |
| 6310 | = | 119 100 | x |
119 100 | x | = | 6310 |
| x | = | 6310 | ÷ | 119 100 |
| = | 6310 | × | 100 119 |
| x | = | 631000 119 |
| x | = | 5302.521008 |
