( | 18000 | + | 8600 | X | ) | ÷ | 2 | = | 66000 | + | 8600 | X | − | 2417 | X |
方程左边 = | 18000 | × | 1 2 | + | 8600 | X | × | 1 2 |
= | 9000 | + | 4300 | X |
9000 | + | 4300 | X | = | 66000 | + | 8600 | X | − | 2417 | X |
方程右边 = | 66000 | + | 6183 | X |
9000 | + | 4300 | X | = | 66000 | + | 6183 | X |
4300 | X | − | 6183 | X | = | 66000 | − | 9000 |
- | 1883 | X | = | 66000 | − | 9000 |
- | 1883 | X | = | 57000 |
- | 57000 | = | 1883 | X |
1883 | X | = | - | 57000 |
X | = | - | 57000 | ÷ | 1883 |
= | - | 57000 | × | 1 1883 |
X | = | - | 57000 1883 |
X | = | - 30.270844 |
