| 1080 | ÷ | ( | 1 | − | 10 100 | ) | × | x | − | 1080 | ÷ | x | = | 3 |
| Multiply both sides of the equation by: | ( | 1 | − | 10 100 | ) |
| 1080 | x | − | 1080 | ÷ | x | × | ( | 1 | − | 10 100 | ) | = | 3 | ( | 1 | − | 10 100 | ) |
| 1080 | x | − | 1080 | ÷ | x | × | 1 | + | 1080 | ÷ | x | × | 10 100 | = | 3 | ( | 1 | − | 10 100 | ) |
| 1080 | x | − | 1080 | ÷ | x | × | 1 | + | 1080 | ÷ | x | × | 10 100 | = | 3 | × | 1 | − | 3 | × | 10 100 |
| 1080 | x | − | 1080 | ÷ | x | + | 108 | ÷ | x | = | 3 | − | 3 10 |
| 1080 | x | − | 1080 | ÷ | x | + | 108 | ÷ | x | = | 27 10 |
