| X | ÷ | 1000 | = | ( | ( | X | − | 95 | ) | ÷ | 1000 | ) | − | 1900 |
| Right side of the equation = | ( | X | − | 95 | ) | ÷ | 1000 | − | 1900 |
| = | X | × | 1 1000 | − | 95 | × | 1 1000 | − | 1900 |
| = | X | × | 1 1000 | − | 19 200 | − | 1900 |
| = | 1 1000 | X | − | 380019 200 |
1 1000 | X | = | 1 1000 | X | − | 380019 200 |
1 1000 | X | − | 1 1000 | X | = | - | 380019 200 |
| 0 | X | = | - | 380019 200 |
