| 1 | − | 1 | ÷ | ( | 1 | + | 50 | ÷ | ( | 5 | x | ) | ) | = | 0 |
| Multiply both sides of the equation by: | ( | 1 | + | 50 | ÷ | ( | 5 | x | ) | ) |
| 1 | ( | 1 | + | 50 | ÷ | ( | 5 | x | ) | ) | − | 1 | = | 0 |
| 1 | × | 1 | + | 1 | × | 50 | ÷ | ( | 5 | x | ) | − | 1 | = | 0 |
| 1 | + | 50 | ÷ | ( | 5 | x | ) | − | 1 | = | 0 |
| 0 | + | 50 | ÷ | ( | 5 | x | ) | = | 0 |
