| 14 | = | 241 200 | ( | 1 | + | 220000 | ÷ | x | ) |
| 14 | = | 241 200 | × | 1 | + | 241 200 | × | 220000 | ÷ | x |
| 14 | = | 241 200 | + | 265100 | ÷ | x |
| Multiply both sides of the equation by: | x |
| 14 | x | = | 241 200 | x | + | 265100 |
| 14 | x | − | 241 200 | x | = | 265100 |
2559 200 | x | = | 265100 |
| x | = | 265100 | ÷ | 2559 200 |
| = | 265100 | × | 200 2559 |
| x | = | 53020000 2559 |
| x | = | 20719.030871 |
