| ( | 29402 | − | 2 | x | ) | ÷ | ( | 2 | x | + | 1 | ) | = | 1 |
| 方程两边同时乘以: | ( | 2 | x | + | 1 | ) |
| ( | 29402 | − | 2 | x | ) | = | 1 | ( | 2 | x | + | 1 | ) |
| 29402 | − | 2 | x | = | 1 | ( | 2 | x | + | 1 | ) |
| 29402 | − | 2 | x | = | 1 | × | 2 | x | + | 1 | × | 1 |
| 29402 | − | 2 | x | = | 2 | x | + | 1 |
| - | 2 | x | − | 2 | x | = | 1 | − | 29402 |
| - | 4 | x | = | 1 | − | 29402 |
| - | 4 | x | = | - | 29401 |
| 29401 | = | 4 | x |
| 4 | x | = | 29401 |
| x | = | 29401 | ÷ | 4 |
| = | 29401 | × | 1 4 |
| x | = | 29401 4 |
