| ( | 10 | x | + | 3 | ) | × | 6528 | = | ( | 30 | + | x | ) | × | 8256 |
| Left side of the equation = | 10 | x | × | 6528 | + | 3 | × | 6528 |
| = | 65280 | x | + | 19584 |
| 65280 | x | + | 19584 | = | ( | 30 | + | x | ) | × | 8256 |
| Right side of the equation = | 30 | × | 8256 | + | x | × | 8256 |
| = | 247680 | + | x | × | 8256 |
| 65280 | x | + | 19584 | = | 247680 | + | 8256 | x |
| 65280 | x | − | 8256 | x | = | 247680 | − | 19584 |
| 57024 | x | = | 247680 | − | 19584 |
| 57024 | x | = | 228096 |
| x | = | 228096 | ÷ | 57024 |
