| ( | 11 | ( | 5 | ÷ | 6 | + | x | ) | ) | ÷ | 2 | = | - | 5 |
| Left side of the equation = | 11 | ( | 5 | ÷ | 6 | + | x | ) | × | 1 2 |
| = | 11 2 | ( | 5 | ÷ | 6 | + | x | ) |
| = | 11 2 | × | 5 | ÷ | 6 | + | 11 2 | x |
| = | 55 12 | + | 11 2 | x |
55 12 | + | 11 2 | x | = | - | 5 |
11 2 | x | = | - | 5 | − | 55 12 |
11 2 | x | = | - | 115 12 |
| x | = | - | 115 12 | ÷ | 11 2 |
| = | - | 115 12 | × | 2 11 |
| = | - | 115 6 | × | 1 11 |
| x | = | - | 115 66 |
| x | = | - 1.742424 |
