( | 15 | − | x | ) | ÷ | 100000 | = | x | ÷ | 22000 | + | ( | x | − | 4 5 | ) | ÷ | 51 5 |
方程左边 = | 15 | × | 1 100000 | − | x | × | 1 100000 |
= | 3 20000 | − | x | × | 1 100000 |
3 20000 | − | 1 100000 | x | = | x | ÷ | 22000 | + | ( | x | − | 4 5 | ) | ÷ | 51 5 |
方程右边 = | 1 22000 | x | + | x | × | 5 51 | − | 4 5 | × | 5 51 |
= | 1 22000 | x | + | x | × | 5 51 | − | 4 51 |
= | 110051 1122000 | x | − | 4 51 |
3 20000 | − | 1 100000 | x | = | 110051 1122000 | x | − | 4 51 |
- | 1 100000 | x | − | 110051 1122000 | x | = | - | 4 51 | − | 3 20000 |
