| ( | 43 | ÷ | 34 | ) | ( | - | 432 | ) | − | y | = | y |
| 方程左边 = | 43 | ÷ | 34 | × | ( | - | 432 | ) | − | y |
| = | 43 34 | ( | - | 432 | ) | − | y |
| = | - | 43 34 | × | 432 | − | y |
| = | - | 9288 17 | − | y |
| - | 9288 17 | − | y | = | y |
| - | y | − | y | = | 9288 17 |
| - | 2 | y | = | 9288 17 |
| - | 9288 17 | = | 2 | y |
| 2 | y | = | - | 9288 17 |
| y | = | - | 9288 17 | ÷ | 2 |
| = | - | 9288 17 | × | 1 2 |
| = | - | 4644 17 | × | 1 |
| y | = | - | 4644 17 |
| y | = | - 273.176471 |
