x | ÷ | 280 | + | 6000 | = | ( | x | + | 1000000 | ) | ÷ | 240 |
方程右边 = | x | × | 1 240 | + | 1000000 | × | 1 240 |
= | x | × | 1 240 | + | 12500 3 |
1 280 | x | + | 6000 | = | 1 240 | x | + | 12500 3 |
1 280 | x | − | 1 240 | x | = | 12500 3 | − | 6000 |
- | 1 1680 | x | = | 12500 3 | − | 6000 |
- | 1 1680 | x | = | - | 5500 3 |
5500 3 | = | 1 1680 | x |
1 1680 | x | = | 5500 3 |
x | = | 5500 3 | ÷ | 1 1680 |
= | 5500 3 | × | 1680 |
= | 5500 | × | 560 |
x | = | 3080000 |
