| ( | 617 10 | − | x | ) | × | 11 10 | + | 73 100 | x | = | 1000571 10000 |
| Left side of the equation = | 617 10 | × | 11 10 | − | x | × | 11 10 | + | 73 100 | x |
| = | 6787 100 | − | x | × | 11 10 | + | 73 100 | x |
| = | 6787 100 | − | 37 100 | x |
6787 100 | − | 37 100 | x | = | 1000571 10000 |
| - | 37 100 | x | = | 1000571 10000 | − | 6787 100 |
| - | 37 100 | x | = | 321871 10000 |
| - | 321871 10000 | = | 37 100 | x |
37 100 | x | = | - | 321871 10000 |
| x | = | - | 321871 10000 | ÷ | 37 100 |
| = | - | 321871 10000 | × | 100 37 |
