| 120000 | ( | x | − | 180 | ) | − | 720 | = | 1480000 |
| Left side of the equation = | 120000 | x | − | 120000 | × | 180 | − | 720 |
| = | 120000 | x | − | 21600000 | − | 720 |
| = | 120000 | x | − | 21600720 |
| 120000 | x | − | 21600720 | = | 1480000 |
| 120000 | x | = | 1480000 | + | 21600720 |
| 120000 | x | = | 23080720 |
| x | = | 23080720 | ÷ | 120000 |
| = | 23080720 | × | 1 120000 |
| = | 288509 | × | 1 1500 |
| x | = | 288509 1500 |
| x | = | 192.339333 |
