9 10 | = | ( | x | x | x | x | x | x | − | x | ) | ÷ | ( | x | x | x | x | x | x | − | 1 | ) |
| Multiply both sides of the equation by: | ( | x | x | x | x | x | x | − | 1 | ) |
9 10 | ( | x | x | x | x | x | x | − | 1 | ) | = | ( | x | x | x | x | x | x | − | x | ) |
9 10 | x | x | x | x | x | x | − | 9 10 | × | 1 | = | ( | x | x | x | x | x | x | − | x | ) |
9 10 | x | x | x | x | x | x | − | 9 10 | × | 1 | = | x | x | x | x | x | x | − | x |
9 10 | x | x | x | x | x | x | − | 9 10 | = | x | x | x | x | x | x | − | x |
