| ( | 29402 | − | 2 | x | ) | ÷ | ( | 2 | x | + | 1 | ) | = | 5 |
| 方程两边同时乘以: | ( | 2 | x | + | 1 | ) |
| ( | 29402 | − | 2 | x | ) | = | 5 | ( | 2 | x | + | 1 | ) |
| 29402 | − | 2 | x | = | 5 | ( | 2 | x | + | 1 | ) |
| 29402 | − | 2 | x | = | 5 | × | 2 | x | + | 5 | × | 1 |
| 29402 | − | 2 | x | = | 10 | x | + | 5 |
| - | 2 | x | − | 10 | x | = | 5 | − | 29402 |
| - | 12 | x | = | 5 | − | 29402 |
| - | 12 | x | = | - | 29397 |
| 29397 | = | 12 | x |
| 12 | x | = | 29397 |
| x | = | 29397 | ÷ | 12 |
| = | 29397 | × | 1 12 |
| = | 9799 | × | 1 4 |
