| x | ÷ | ( | x | + | 11200 | ) | = | 15 100 |
| Multiply both sides of the equation by: | ( | x | + | 11200 | ) |
| x | = | 15 100 | ( | x | + | 11200 | ) |
| x | = | 15 100 | x | + | 15 100 | × | 11200 |
| x | = | 15 100 | x | + | 1680 |
| x | − | 15 100 | x | = | 1680 |
17 20 | x | = | 1680 |
| x | = | 1680 | ÷ | 17 20 |
| = | 1680 | × | 20 17 |
| x | = | 33600 17 |
| x | = | 1976.470588 |
