| 22 | ÷ | X | − | 22 | ÷ | ( | X | − | 1 | ) | = | 12 |
| Multiply both sides of the equation by: | X |
| 22 | − | 22 | ÷ | ( | X | − | 1 | ) | × | X | = | 12 | X |
| Multiply both sides of the equation by: | ( | X | − | 1 | ) |
| 22 | ( | X | − | 1 | ) | − | 22 | X | = | 12 | X | ( | X | − | 1 | ) |
| 22 | X | − | 22 | × | 1 | − | 22 | X | = | 12 | X | ( | X | − | 1 | ) |
| 22 | X | − | 22 | × | 1 | − | 22 | X | = | 12 | X | X | − | 12 | X | × | 1 |
| 22 | X | − | 22 | − | 22 | X | = | 12 | X | X | − | 12 | X |
| 0 | X | − | 22 | = | 12 | X | X | − | 12 | X |
