| 168 | = | 60 | × | 222 5 | ÷ | 12 | × | ( | 1 | − | x | ) |
| Right side of the equation = | 222 | ( | 1 | − | x | ) |
| 168 | = | 222 | ( | 1 | − | x | ) |
| Right side of the equation = | 222 | × | 1 | − | 222 | x |
| = | 222 | − | 222 | x |
| 168 | = | 222 | − | 222 | x |
| 222 | x | = | 222 | − | 168 |
| 222 | x | = | 54 |
| x | = | 54 | ÷ | 222 |
| = | 54 | × | 1 222 |
