| ( | 5220 | − | x | ) | ÷ | x | = | 208 500 |
| Multiply both sides of the equation by: | x |
| ( | 5220 | − | x | ) | = | 208 500 | x |
| 5220 | − | x | = | 208 500 | x |
| - | x | − | 208 500 | x | = | - | 5220 |
| - | 177 125 | x | = | - | 5220 |
| 5220 | = | 177 125 | x |
177 125 | x | = | 5220 |
| x | = | 5220 | ÷ | 177 125 |
| = | 5220 | × | 125 177 |
| = | 1740 | × | 125 59 |
| x | = | 217500 59 |
| x | = | 3686.440678 |
