| y | ÷ | 3 | − | ( | ( | y | − | 1 | ) | ÷ | 6 | ) | = | 1 | − | ( | ( | 2 | y | ) | ÷ | 3 | ) |
| 方程左边 = | 1 3 | y | − | ( | y | − | 1 | ) | ÷ | 6 |
| = | 1 3 | y | − | y | × | 1 6 | + | 1 | × | 1 6 |
| = | 1 3 | y | − | y | × | 1 6 | + | 1 6 |
| = | 1 6 | y | + | 1 6 |
1 6 | y | + | 1 6 | = | 1 | − | ( | ( | 2 | y | ) | ÷ | 3 | ) |
| 方程右边 = | 1 | − | ( | 2 | y | ) | ÷ | 3 |
| = | 1 | − | 2 | y | × | 1 3 |
| = | 1 | − | 2 3 | y |
1 6 | y | + | 1 6 | = | 1 | − | 2 3 | y |
1 6 | y | + | 2 3 | y | = | 1 | − | 1 6 |
5 6 | y | = | 1 | − | 1 6 |
5 6 | y | = | 5 6 |
| y | = | 5 6 | ÷ | 5 6 |
| = | 5 6 | × | 6 5 |
| = | 1 | × | 1 |
| y | = | 1 |
