| 100 | x | ÷ | 120 | × | ( | 14 | − | x | ) | = | 1 | ÷ | 3 |
| Left side of the equation = | 5 6 | x | ( | 14 | − | x | ) |
5 6 | x | ( | 14 | − | x | ) | = | 1 | ÷ | 3 |
| Left side of the equation = | 5 6 | x | × | 14 | − | 5 6 | x | x |
| = | 35 3 | x | − | 5 6 | x | x |
35 3 | x | − | 5 6 | x | x | = | 1 | ÷ | 3 |
| Right side of the equation = | 1 3 |
35 3 | x | − | 5 6 | x | x | = | 1 3 |
