| - | 41800 | + | 30000 | + | x | − | x | × | 10 100 | ÷ | 4 | − | 4500 | = | 3000 |
| Left side of the equation = | - | 41800 | + | 30000 | + | x | − | x | × | 1 40 | − | 4500 |
| = | - | 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 |
