11 200 | = | x | ÷ | ( | 6000 | + | x | ) |
| Multiply both sides of the equation by: | ( | 6000 | + | x | ) |
11 200 | ( | 6000 | + | x | ) | = | x |
11 200 | × | 6000 | + | 11 200 | x | = | x |
| 330 | + | 11 200 | x | = | x |
11 200 | x | − | x | = | - | 330 |
| - | 189 200 | x | = | - | 330 |
| 330 | = | 189 200 | x |
189 200 | x | = | 330 |
| x | = | 330 | ÷ | 189 200 |
| = | 330 | × | 200 189 |
| = | 110 | × | 200 63 |
| x | = | 22000 63 |
| x | = | 349.206349 |
