| - | 2 | ( | ( | 11 | y | − | 12 | ) | ÷ | 5 | ) | = | y | + | 16 |
| 方程左边 = | - | 2 | ( | 11 | y | − | 12 | ) | ÷ | 5 |
| = | - | 2 5 | ( | 11 | y | − | 12 | ) |
| = | - | 2 5 | × | 11 | y | + | 2 5 | × | 12 |
| = | - | 22 5 | y | + | 24 5 |
| - | 22 5 | y | + | 24 5 | = | y | + | 16 |
| - | 22 5 | y | − | y | = | 16 | − | 24 5 |
| - | 27 5 | y | = | 16 | − | 24 5 |
| - | 27 5 | y | = | 56 5 |
| - | 56 5 | = | 27 5 | y |
27 5 | y | = | - | 56 5 |
| y | = | - | 56 5 | ÷ | 27 5 |
| = | - | 56 5 | × | 5 27 |
| = | - | 56 | × | 1 27 |
| y | = | - | 56 27 |
| y | = | - 2.074074 |
