| ( | x | ÷ | 397 100 | ) | ÷ | ( | x | ÷ | 397 100 | + | 33 10 | ÷ | 127 100 | ) | = | 1 100 |
| 方程两边同时乘以: | ( | x | ÷ | 397 100 | + | 33 10 | ÷ | 127 100 | ) |
| ( | x | ÷ | 397 100 | ) | = | 1 100 | ( | x | ÷ | 397 100 | + | 33 10 | ÷ | 127 100 | ) |
| x | ÷ | 397 100 | = | 1 100 | ( | x | ÷ | 397 100 | + | 33 10 | ÷ | 127 100 | ) |
| x | ÷ | 397 100 | = | 1 100 | x | ÷ | 397 100 | + | 1 100 | × | 33 10 | ÷ | 127 100 |
| x | × | 100 397 | = | 1 397 | x | + | 33 1270 |
100 397 | x | − | 1 397 | x | = | 33 1270 |
99 397 | x | = | 33 1270 |
| x | = | 33 1270 | ÷ | 99 397 |
| = | 33 1270 | × | 397 99 |
| = | 1 1270 | × | 397 3 |
