| y | = | ( | 196 | − | 4 | ( | 46 | − | ( | 6 | y | ÷ | 4 | ) | ) | ) | ÷ | 6 |
| 方程右边 = | 196 | × | 1 6 | − | 4 | ( | 46 | − | ( | 6 | y | ÷ | 4 | ) | ) | × | 1 6 |
| = | 98 3 | − | 2 3 | ( | 46 | − | ( | 6 | y | ÷ | 4 | ) | ) |
| = | 98 3 | − | 2 3 | × | 46 | + | 2 3 | ( | 6 | y | ÷ | 4 | ) |
| = | 98 3 | − | 92 3 | + | 2 3 | ( | 6 | y | ÷ | 4 | ) |
| = | 2 | + | 2 3 | ( | 6 | y | ÷ | 4 | ) |
| = | 2 | + | 2 3 | × | 6 | y | ÷ | 4 |
| = | 2 | + | 1 | y |
| y | = | 2 | + | 1 | y |
| y | − | 1 | y | = | 2 |
| 0 | y | = | 2 |
