| 4 | ÷ | ( | x | ( | x | x | + | 1 | ) | ( | 1 | ÷ | 2 | ) | ) | = | 1 |
| Multiply both sides of the equation by: | ( | x | ( | x | x | + | 1 | ) | ( | 1 | ÷ | 2 | ) | ) |
| 4 | = | 1 | ( | x | ( | x | x | + | 1 | ) | ( | 1 | ÷ | 2 | ) | ) |
| 4 | = | 1 | x | ( | x | x | + | 1 | ) | ( | 1 | ÷ | 2 | ) |
| 4 | = | 1 | x | x | x | ( | 1 | ÷ | 2 | ) | + | 1 | x | × | 1 | ( | 1 | ÷ | 2 | ) |
| 4 | = | 1 | x | x | x | ( | 1 | ÷ | 2 | ) | + | 1 | x | ( | 1 | ÷ | 2 | ) |
| 4 | = | 1 | x | x | x | × | 1 | ÷ | 2 | + | 1 | x | ( | 1 | ÷ | 2 | ) |
| 4 | = | 1 2 | x | x | x | + | 1 | x | ( | 1 | ÷ | 2 | ) |
| 4 | = | 1 2 | x | x | x | + | 1 | x | × | 1 | ÷ | 2 |
| 4 | = | 1 2 | x | x | x | + | 1 2 | x |
