| 1 | ÷ | x | − | 10 | + | 1 | ÷ | x | − | 6 | = | 1 | ÷ | x | − | 7 | + | 1 | ÷ | x | − | 9 |
| Multiply both sides of the equation by: | x |
| 1 | − | 10 | x | + | 1 | ÷ | 1 | × | 1 | − | 6 | x | = | 1 | ÷ | 1 | × | 1 | − | 7 | x | + | 1 | ÷ | 1 | × | 1 | − | 9 | x |
| - | 10 | x | − | 6 | x | + | 7 | x | + | 9 | x | = | 1 | ÷ | 1 | × | 1 | + | 1 | ÷ | 1 | × | 1 | − | 1 | − | 1 | ÷ | 1 | × | 1 |
| - | 10 | x | − | 6 | x | + | 7 | x | + | 9 | x | = | 1 | + | 1 | − | 1 | − | 1 |
| - | 0 | x | = | 1 | + | 1 | − | 1 | − | 1 |
| - | 0 | x | = | 0 |
