| ( | 29402 | − | 2 | x | ) | ÷ | ( | 2 | x | + | 1 | ) | = | 3 |
| 方程两边同时乘以: | ( | 2 | x | + | 1 | ) |
| ( | 29402 | − | 2 | x | ) | = | 3 | ( | 2 | x | + | 1 | ) |
| 29402 | − | 2 | x | = | 3 | ( | 2 | x | + | 1 | ) |
| 29402 | − | 2 | x | = | 3 | × | 2 | x | + | 3 | × | 1 |
| 29402 | − | 2 | x | = | 6 | x | + | 3 |
| - | 2 | x | − | 6 | x | = | 3 | − | 29402 |
| - | 8 | x | = | 3 | − | 29402 |
| - | 8 | x | = | - | 29399 |
| 29399 | = | 8 | x |
| 8 | x | = | 29399 |
| x | = | 29399 | ÷ | 8 |
| = | 29399 | × | 1 8 |
| x | = | 29399 8 |
