| 75 | × | 27 2 | = | ( | 27 2 | − | x | ) | × | 82 | − | x |
| Left side of the equation = | 2025 2 |
2025 2 | = | ( | 27 2 | − | x | ) | × | 82 | − | x |
| Right side of the equation = | 27 2 | × | 82 | − | x | × | 82 | − | x |
| = | 1107 | − | x | × | 82 | − | x |
| = | 1107 | − | 83 | x |
2025 2 | = | 1107 | − | 83 | x |
| 83 | x | = | 1107 | − | 2025 2 |
| 83 | x | = | 189 2 |
| x | = | 189 2 | ÷ | 83 |
| = | 189 2 | × | 1 83 |
| x | = | 189 166 |
| x | = | 1.138554 |
