方程左边 = | 45 100 | x | + | 288 5 |
45 100 | x | + | 288 5 | = | ( | 80 | + | x | ) | × | 58 100 |
方程右边 = | 80 | × | 58 100 | + | x | × | 58 100 |
= | 232 5 | + | x | × | 58 100 |
45 100 | x | + | 288 5 | = | 232 5 | + | 58 100 | x |
45 100 | x | − | 58 100 | x | = | 232 5 | − | 288 5 |
- | 13 100 | x | = | 232 5 | − | 288 5 |
- | 13 100 | x | = | - | 56 5 |
56 5 | = | 13 100 | x |
13 100 | x | = | 56 5 |
x | = | 56 5 | ÷ | 13 100 |
= | 56 5 | × | 100 13 |
= | 56 | × | 20 13 |
