| 1400 | ÷ | 3 | × | x | − | 400 | ÷ | ( | x | − | 2 | ) | = | 1 |
| Multiply both sides of the equation by: | ( | x | − | 2 | ) |
| 1400 | ÷ | 3 | × | x | ( | x | − | 2 | ) | − | 400 | = | 1 | ( | x | − | 2 | ) |
| 1400 | ÷ | 3 | × | x | x | − | 1400 | ÷ | 3 | × | x | × | 2 | − | 400 | = | 1 | ( | x | − | 2 | ) |
| 1400 | ÷ | 3 | × | x | x | − | 1400 | ÷ | 3 | × | x | × | 2 | − | 400 | = | 1 | x | − | 1 | × | 2 |
