| ( | 1211 4 | − | x | ) | ÷ | x | = | 1303 1000 |
| 方程两边同时乘以: | x |
| ( | 1211 4 | − | x | ) | = | 1303 1000 | x |
1211 4 | − | x | = | 1303 1000 | x |
| - | x | − | 1303 1000 | x | = | - | 1211 4 |
| - | 2303 1000 | x | = | - | 1211 4 |
1211 4 | = | 2303 1000 | x |
2303 1000 | x | = | 1211 4 |
| x | = | 1211 4 | ÷ | 2303 1000 |
| = | 1211 4 | × | 1000 2303 |
