| ( | X | − | 1860 | − | 5000 | ) | × | 1 10 | − | 241 | = | X | − | 12000 |
| Left side of the equation = | X | × | 1 10 | − | 1860 | × | 1 10 | − | 5000 | × | 1 10 | − | 241 |
| = | X | × | 1 10 | − | 186 | − | 500 | − | 241 |
| = | 1 10 | X | − | 927 |
1 10 | X | − | 927 | = | X | − | 12000 |
1 10 | X | − | X | = | - | 12000 | + | 927 |
| - | 9 10 | X | = | - | 12000 | + | 927 |
| - | 9 10 | X | = | - | 11073 |
| 11073 | = | 9 10 | X |
9 10 | X | = | 11073 |
| X | = | 11073 | ÷ | 9 10 |
| = | 11073 | × | 10 9 |
| = | 3691 | × | 10 3 |
| X | = | 36910 3 |
| X | = | 12303.333333 |
