| 12 | ÷ | ( | 24 | + | ( | 12 | − | 24 | x | ) | ÷ | x | ) | = | x |
| Multiply both sides of the equation by: | ( | 24 | + | ( | 12 | − | 24 | x | ) | ÷ | x | ) |
| 12 | = | x | ( | 24 | + | ( | 12 | − | 24 | x | ) | ÷ | x | ) |
| 12 | = | x | × | 24 | + | x | ( | 12 | − | 24 | x | ) | ÷ | x |
| 12 | = | 24 | x | + | 1 | × | 12 | ÷ | 1 | − | 1 | × | 24 | x | ÷ | 1 |
| 12 | = | 24 | x | + | 12 | − | 24 | x |
| 12 | = | 0 | x | + | 12 |
| = | 12 | − | 12 |
