| 11180 | = | ( | 200000 | ÷ | ( | 1 | + | x | ) | ) | x |
| 11180 | = | 200000 | ÷ | ( | 1 | + | x | ) | × | x |
| Multiply both sides of the equation by: | ( | 1 | + | x | ) |
| 11180 | ( | 1 | + | x | ) | = | 200000 | x |
| 11180 | × | 1 | + | 11180 | x | = | 200000 | x |
| 11180 | + | 11180 | x | = | 200000 | x |
| 11180 | x | − | 200000 | x | = | - | 11180 |
| - | 188820 | x | = | - | 11180 |
| 11180 | = | 188820 | x |
| 188820 | x | = | 11180 |
| x | = | 11180 | ÷ | 188820 |
| = | 11180 | × | 1 188820 |
| = | 559 | × | 1 9441 |
| x | = | 559 9441 |
| x | = | 0.05921 |
