| 18000 | ( | 1 | − | x | ÷ | ( | 5080 | ÷ | 30 | ) | ) | = | 0 |
| 18000 | × | 1 | − | 18000 | x | ÷ | ( | 5080 | ÷ | 30 | ) | = | 0 |
| 18000 | − | 18000 | x | ÷ | ( | 5080 | ÷ | 30 | ) | = | 0 |
| Multiply both sides of the equation by: | ( | 5080 | ÷ | 30 | ) |
| 18000 | ( | 5080 | ÷ | 30 | ) | − | 18000 | x | = | 0 |
| 18000 | × | 5080 | ÷ | 30 | − | 18000 | x | = | 0 |
| 3048000 | − | 18000 | x | = | 0 |
| - | 18000 | x | = | 0 | − | 3048000 |
| - | 18000 | x | = | - | 3048000 |
| 3048000 | = | 18000 | x |
| 18000 | x | = | 3048000 |
| x | = | 3048000 | ÷ | 18000 |
| = | 3048000 | × | 1 18000 |
| = | 508 | × | 1 3 |
| x | = | 508 3 |
| x | = | 169.333333 |
