| 4 | ÷ | ( | x | + | 8 | ) | − | 5 | = | 32 |
| 方程两边同时乘以: | ( | x | + | 8 | ) |
| 4 | − | 5 | ( | x | + | 8 | ) | = | 32 | ( | x | + | 8 | ) |
| 4 | − | 5 | x | − | 5 | × | 8 | = | 32 | ( | x | + | 8 | ) |
| 4 | − | 5 | x | − | 5 | × | 8 | = | 32 | x | + | 32 | × | 8 |
| 4 | − | 5 | x | − | 40 | = | 32 | x | + | 256 |
| - | 36 | − | 5 | x | = | 32 | x | + | 256 |
| - | 5 | x | − | 32 | x | = | 256 | + | 36 |
| - | 37 | x | = | 256 | + | 36 |
| - | 37 | x | = | 292 |
| - | 292 | = | 37 | x |
| 37 | x | = | - | 292 |
| x | = | - | 292 | ÷ | 37 |
| = | - | 292 | × | 1 37 |
| x | = | - | 292 37 |
