| X | − | 1 100 | X | − | 14 | − | 4 100 | X | − | 19 10 | − | 53 1000 | X | = | 679 10 |
| Left side of the equation = | 897 1000 | X | − | 159 10 |
897 1000 | X | − | 159 10 | = | 679 10 |
897 1000 | X | = | 679 10 | + | 159 10 |
897 1000 | X | = | 419 5 |
| X | = | 419 5 | ÷ | 897 1000 |
| = | 419 5 | × | 1000 897 |
| = | 419 | × | 200 897 |
| X | = | 83800 897 |
| X | = | 93.42252 |
