( | 47 100 | − | x | ) | ÷ | 9 20 | = | ( | 153 100 | − | x | ) | ÷ | 137 100 |
方程左边 = | 47 100 | × | 20 9 | − | x | × | 20 9 |
= | 47 45 | − | x | × | 20 9 |
47 45 | − | 20 9 | x | = | ( | 153 100 | − | x | ) | ÷ | 137 100 |
方程右边 = | 153 100 | × | 100 137 | − | x | × | 100 137 |
= | 153 137 | − | x | × | 100 137 |
47 45 | − | 20 9 | x | = | 153 137 | − | 100 137 | x |
- | 20 9 | x | + | 100 137 | x | = | 153 137 | − | 47 45 |
- | 1840 1233 | x | = | 153 137 | − | 47 45 |
- | 1840 1233 | x | = | 446 6165 |
- | 446 6165 | = | 1840 1233 | x |
1840 1233 | x | = | - | 446 6165 |
x | = | - | 446 6165 | ÷ | 1840 1233 |
= | - | 446 6165 | × | 1233 1840 |
= | - | 223 685 | × | 137 920 |
x | = | - | 30551 630200 |
x | = | - | 223 4600 |
