| ( | X | − | 1023 | − | 5000 | ) | × | 3 100 | = | X | − | 408609 100 |
| Left side of the equation = | X | × | 3 100 | − | 1023 | × | 3 100 | − | 5000 | × | 3 100 |
| = | X | × | 3 100 | − | 3069 100 | − | 150 |
| = | 3 100 | X | − | 18069 100 |
3 100 | X | − | 18069 100 | = | X | − | 408609 100 |
3 100 | X | − | X | = | - | 408609 100 | + | 18069 100 |
| - | 97 100 | X | = | - | 408609 100 | + | 18069 100 |
| - | 97 100 | X | = | - | 19527 5 |
19527 5 | = | 97 100 | X |
97 100 | X | = | 19527 5 |
| X | = | 19527 5 | ÷ | 97 100 |
| = | 19527 5 | × | 100 97 |
| = | 19527 | × | 20 97 |
| X | = | 390540 97 |
| X | = | 4026.185567 |
