| ( | X | − | 5000 | − | 1860 | ) | × | 10 | = | X | − | 12000 | − | 1860 |
| Left side of the equation = | X | × | 10 | − | 5000 | × | 10 | − | 1860 | × | 10 |
| = | X | × | 10 | − | 50000 | − | 18600 |
| = | 10 | X | − | 68600 |
| 10 | X | − | 68600 | = | X | − | 12000 | − | 1860 |
| Right side of the equation = | X | − | 13860 |
| 10 | X | − | 68600 | = | X | − | 13860 |
| 10 | X | − | X | = | - | 13860 | + | 68600 |
| 9 | X | = | - | 13860 | + | 68600 |
| 9 | X | = | 54740 |
| X | = | 54740 | ÷ | 9 |
| = | 54740 | × | 1 9 |
| X | = | 54740 9 |
| X | = | 6082.222222 |
