| x | − | ( | x | − | 5000 | ) | × | 3 100 | − | 9339 25 | = | 8000 |
| Left side of the equation = | x | − | x | × | 3 100 | + | 5000 | × | 3 100 | − | 9339 25 |
| = | x | − | x | × | 3 100 | + | 150 | − | 9339 25 |
| = | 97 100 | x | − | 5589 25 |
97 100 | x | − | 5589 25 | = | 8000 |
97 100 | x | = | 8000 | + | 5589 25 |
97 100 | x | = | 205589 25 |
| x | = | 205589 25 | ÷ | 97 100 |
| = | 205589 25 | × | 100 97 |
| = | 205589 | × | 4 97 |
| x | = | 822356 97 |
| x | = | 8477.896907 |
