| ( | 5 | y | + | 1 | ) | ÷ | 6 | = | ( | 9 | y | + | 1 | ) | ÷ | 8 | − | ( | 1 | − | y | ) | ÷ | 3 |
| 方程左边 = | 5 | y | × | 1 6 | + | 1 | × | 1 6 |
| = | 5 6 | y | + | 1 6 |
5 6 | y | + | 1 6 | = | ( | 9 | y | + | 1 | ) | ÷ | 8 | − | ( | 1 | − | y | ) | ÷ | 3 |
| 方程右边 = | 9 | y | × | 1 8 | + | 1 | × | 1 8 | − | ( | 1 | − | y | ) | × | 1 3 |
| = | 9 8 | y | + | 1 8 | − | ( | 1 | − | y | ) | × | 1 3 |
| = | 9 8 | y | + | 1 8 | − | 1 | × | 1 3 | + | y | × | 1 3 |
| = | 9 8 | y | + | 1 8 | − | 1 3 | + | y | × | 1 3 |
| = | 35 24 | y | − | 5 24 |
5 6 | y | + | 1 6 | = | 35 24 | y | − | 5 24 |
5 6 | y | − | 35 24 | y | = | - | 5 24 | − | 1 6 |
| - | 5 8 | y | = | - | 5 24 | − | 1 6 |
| - | 5 8 | y | = | - | 3 8 |
3 8 | = | 5 8 | y |
5 8 | y | = | 3 8 |
| y | = | 3 8 | ÷ | 5 8 |
| = | 3 8 | × | 8 5 |
| = | 3 | × | 1 5 |
| y | = | 3 5 |
| y | = | 0.6 |
