| 24 | ( | 15000 | ÷ | ( | x | + | 15000 | ) | ) | = | 51 25 |
| 24 | × | 15000 | ÷ | ( | x | + | 15000 | ) | = | 51 25 |
| 360000 | ÷ | ( | x | + | 15000 | ) | = | 51 25 |
| Multiply both sides of the equation by: | ( | x | + | 15000 | ) |
| 360000 | = | 51 25 | ( | x | + | 15000 | ) |
| 360000 | = | 51 25 | x | + | 51 25 | × | 15000 |
| 360000 | = | 51 25 | x | + | 30600 |
| - | 51 25 | x | = | 30600 | − | 360000 |
| - | 51 25 | x | = | - | 329400 |
| 329400 | = | 51 25 | x |
51 25 | x | = | 329400 |
| x | = | 329400 | ÷ | 51 25 |
| = | 329400 | × | 25 51 |
| = | 109800 | × | 25 17 |
| x | = | 2745000 17 |
| x | = | 161470.588235 |
