X | ÷ | 135 | − | ( | 100 | − | X | ) | ÷ | 1000 | = | 57 200 |
方程左边 = | 1 135 | X | − | 100 | × | 1 1000 | + | X | × | 1 1000 |
= | 1 135 | X | − | 1 10 | + | X | × | 1 1000 |
= | 227 27000 | X | − | 1 10 |
227 27000 | X | − | 1 10 | = | 57 200 |
227 27000 | X | = | 57 200 | + | 1 10 |
227 27000 | X | = | 77 200 |
X | = | 77 200 | ÷ | 227 27000 |
= | 77 200 | × | 27000 227 |
= | 77 | × | 135 227 |
X | = | 10395 227 |
X | = | 45.792952 |
