2 25 | X | + | 91 2000 | ( | 5000000 | − | X | ) | = | 29000 |
| Left side of the equation = | 2 25 | X | + | 91 2000 | × | 5000000 | − | 91 2000 | X |
| = | 2 25 | X | + | 227500 | − | 91 2000 | X |
| = | 69 2000 | X | + | 227500 |
69 2000 | X | + | 227500 | = | 29000 |
69 2000 | X | = | 29000 | − | 227500 |
69 2000 | X | = | - | 198500 |
| X | = | - | 198500 | ÷ | 69 2000 |
| = | - | 198500 | × | 2000 69 |
| X | = | - | 397000000 69 |
| X | = | - 5753623.188406 |
