| ( | 10383 | − | x | ) | ÷ | x | = | 8 500 |
| Multiply both sides of the equation by: | x |
| ( | 10383 | − | x | ) | = | 8 500 | x |
| 10383 | − | x | = | 8 500 | x |
| - | x | − | 8 500 | x | = | - | 10383 |
| - | 127 125 | x | = | - | 10383 |
| 10383 | = | 127 125 | x |
127 125 | x | = | 10383 |
| x | = | 10383 | ÷ | 127 125 |
| = | 10383 | × | 125 127 |
| x | = | 1297875 127 |
| x | = | 10219.488189 |
