| ( | X | − | 1240 | − | 5000 | ) | × | 1 10 | = | X | − | 9494 | − | 1240 |
| Left side of the equation = | X | × | 1 10 | − | 1240 | × | 1 10 | − | 5000 | × | 1 10 |
| = | X | × | 1 10 | − | 124 | − | 500 |
| = | 1 10 | X | − | 624 |
1 10 | X | − | 624 | = | X | − | 9494 | − | 1240 |
| Right side of the equation = | X | − | 10734 |
1 10 | X | − | 624 | = | X | − | 10734 |
1 10 | X | − | X | = | - | 10734 | + | 624 |
| - | 9 10 | X | = | - | 10734 | + | 624 |
| - | 9 10 | X | = | - | 10110 |
| 10110 | = | 9 10 | X |
9 10 | X | = | 10110 |
| X | = | 10110 | ÷ | 9 10 |
| = | 10110 | × | 10 9 |
| = | 3370 | × | 10 3 |
