2500 | − | 250 | x | ÷ | 2000 | + | 200 | x | = | 2500 | − | 2500 | x | ÷ | 1200 | + | 2500 | x |
方程左边 = | 2500 | − | 1 8 | x | + | 200 | x |
= | 2500 | + | 1599 8 | x |
2500 | + | 1599 8 | x | = | 2500 | − | 2500 | x | ÷ | 1200 | + | 2500 | x |
方程右边 = | 2500 | − | 25 12 | x | + | 2500 | x |
= | 2500 | + | 29975 12 | x |
2500 | + | 1599 8 | x | = | 2500 | + | 29975 12 | x |
1599 8 | x | − | 29975 12 | x | = | 2500 | − | 2500 |
- | 55153 24 | x | = | 2500 | − | 2500 |
- | 55153 24 | x | = | 0 |
- | 0 | = | 55153 24 | x |
55153 24 | x | = | - | 0 |
x | = | - | 0 | ÷ | 55153 24 |
= | - | 0 | × | 24 55153 |
x | = | 0 |
