方程左边 = | 1000 | + | x | × | 587 10 |
1000 | + | 587 10 | x | = | ( | 100 | + | x | ) | × | 25 |
方程右边 = | 100 | × | 25 | + | x | × | 25 |
= | 2500 | + | x | × | 25 |
1000 | + | 587 10 | x | = | 2500 | + | 25 | x |
587 10 | x | − | 25 | x | = | 2500 | − | 1000 |
337 10 | x | = | 2500 | − | 1000 |
337 10 | x | = | 1500 |
x | = | 1500 | ÷ | 337 10 |
= | 1500 | × | 10 337 |
