| ( | 21 2 | X | ) | − | ( | 1400000 | + | 2 | X | + | 16 5 | X | ) | = | 0 |
| Left side of the equation = | 21 2 | X | − | ( | 1400000 | + | 2 | X | + | 16 5 | X | ) |
| = | 21 2 | X | − | 1400000 | − | 2 | X | − | 16 5 | X |
| = | 53 10 | X | − | 1400000 |
53 10 | X | − | 1400000 | = | 0 |
53 10 | X | = | 0 | + | 1400000 |
53 10 | X | = | 1400000 |
| X | = | 1400000 | ÷ | 53 10 |
| = | 1400000 | × | 10 53 |
| X | = | 14000000 53 |
| X | = | 264150.943396 |
