| ( | X | − | 1860 | − | 5000 | ) | × | 1 10 | = | X | − | 10950 |
| Left side of the equation = | X | × | 1 10 | − | 1860 | × | 1 10 | − | 5000 | × | 1 10 |
| = | X | × | 1 10 | − | 186 | − | 500 |
| = | 1 10 | X | − | 686 |
1 10 | X | − | 686 | = | X | − | 10950 |
1 10 | X | − | X | = | - | 10950 | + | 686 |
| - | 9 10 | X | = | - | 10950 | + | 686 |
| - | 9 10 | X | = | - | 10264 |
| 10264 | = | 9 10 | X |
9 10 | X | = | 10264 |
| X | = | 10264 | ÷ | 9 10 |
| = | 10264 | × | 10 9 |
| X | = | 102640 9 |
| X | = | 11404.444444 |
