| 60 | = | 5 | ÷ | 12 | × | ( | x | − | x | ÷ | 5 | ) |
| Right side of the equation = | 5 12 | ( | x | − | x | ÷ | 5 | ) |
| 60 | = | 5 12 | ( | x | − | x | ÷ | 5 | ) |
| Right side of the equation = | 5 12 | x | − | 5 12 | x | ÷ | 5 |
| = | 5 12 | x | − | 1 12 | x |
| = | 1 3 | x |
| 60 | = | 1 3 | x |
| - | 1 3 | x | = | - | 60 |
| 60 | = | 1 3 | x |
1 3 | x | = | 60 |
| x | = | 60 | ÷ | 1 3 |
| = | 60 | × | 3 |
| x | = | 180 |
