| 100 | = | 300 | X | − | 2800000 | + | 160 | X |
| Right side of the equation = | 460 | X | − | 2800000 |
| 100 | = | 460 | X | − | 2800000 |
| - | 460 | X | = | - | 2800000 | − | 100 |
| - | 460 | X | = | - | 2800100 |
| 2800100 | = | 460 | X |
| 460 | X | = | 2800100 |
| X | = | 2800100 | ÷ | 460 |
| = | 2800100 | × | 1 460 |
| = | 140005 | × | 1 23 |
| X | = | 140005 23 |
| X | = | 6087.173913 |
