| - | 41800 | + | 30000 | − | 4500 | + | X | − | X | × | 10 100 | ÷ | 4 | = | 3000 |
| Left side of the equation = | - | 41800 | + | 30000 | − | 4500 | + | X | − | X | × | 1 40 |
| = | - | 16300 | + | 39 40 | X |
| - | 16300 | + | 39 40 | X | = | 3000 |
39 40 | X | = | 3000 | + | 16300 |
39 40 | X | = | 19300 |
| X | = | 19300 | ÷ | 39 40 |
| = | 19300 | × | 40 39 |
| X | = | 772000 39 |
| X | = | 19794.871795 |
