| ( | 321 | − | x | ) | ÷ | x | = | 383 500 |
| Multiply both sides of the equation by: | x |
| ( | 321 | − | x | ) | = | 383 500 | x |
| 321 | − | x | = | 383 500 | x |
| - | x | − | 383 500 | x | = | - | 321 |
| - | 883 500 | x | = | - | 321 |
| 321 | = | 883 500 | x |
883 500 | x | = | 321 |
| x | = | 321 | ÷ | 883 500 |
| = | 321 | × | 500 883 |
| x | = | 160500 883 |
| x | = | 181.766704 |
