| 1 | ÷ | 6 | × | ( | x | + | 30 | ÷ | 60 | ) | + | x | ÷ | 4 | = | 1 |
| Left side of the equation = | 1 6 | ( | x | + | 30 | ÷ | 60 | ) | + | x | × | 1 4 |
1 6 | ( | x | + | 30 | ÷ | 60 | ) | + | 1 4 | x | = | 1 |
| Left side of the equation = | 1 6 | x | + | 1 6 | × | 30 | ÷ | 60 | + | 1 4 | x |
| = | 1 6 | x | + | 1 12 | + | 1 4 | x |
| = | 5 12 | x | + | 1 12 |
5 12 | x | + | 1 12 | = | 1 |
5 12 | x | = | 1 | − | 1 12 |
5 12 | x | = | 11 12 |
| x | = | 11 12 | ÷ | 5 12 |
| = | 11 12 | × | 12 5 |
| = | 11 | × | 1 5 |
| x | = | 11 5 |
| x | = | 2.2 |
