x | ÷ | 91 500 | = | ( | x | − | 18 | ) | ÷ | 9 500 |
方程右边 = | x | × | 500 9 | − | 18 | × | 500 9 |
= | x | × | 500 9 | − | 1000 |
500 91 | x | = | 500 9 | x | − | 1000 |
500 91 | x | − | 500 9 | x | = | - | 1000 |
- | 41000 819 | x | = | - | 1000 |
1000 | = | 41000 819 | x |
41000 819 | x | = | 1000 |
x | = | 1000 | ÷ | 41000 819 |
= | 1000 | × | 819 41000 |
= | 1 | × | 819 41 |
x | = | 819 41 |
x | = | 19.97561 |
