| x | ÷ | ( | 1807 | − | x | ) | = | 309 500 |
| Multiply both sides of the equation by: | ( | 1807 | − | x | ) |
| x | = | 309 500 | ( | 1807 | − | x | ) |
| x | = | 309 500 | × | 1807 | − | 309 500 | x |
| x | = | 558363 500 | − | 309 500 | x |
| x | + | 309 500 | x | = | 558363 500 |
809 500 | x | = | 558363 500 |
| x | = | 558363 500 | ÷ | 809 500 |
| = | 558363 500 | × | 500 809 |
| = | 558363 | × | 1 809 |
| x | = | 558363 809 |
| x | = | 690.189122 |
