| 6 | ÷ | ( | 59 | + | x | ) | = | 4 | ÷ | ( | 4 | + | x | ) |
| 方程两边同时乘以: | ( | 59 | + | x | ) | , | ( | 4 | + | x | ) |
| 6 | ( | 4 | + | x | ) | = | 4 | ( | 59 | + | x | ) |
| 6 | × | 4 | + | 6 | x | = | 4 | ( | 59 | + | x | ) |
| 6 | × | 4 | + | 6 | x | = | 4 | × | 59 | + | 4 | x |
| 24 | + | 6 | x | = | 236 | + | 4 | x |
| 6 | x | − | 4 | x | = | 236 | − | 24 |
| 2 | x | = | 236 | − | 24 |
| 2 | x | = | 212 |
| x | = | 212 | ÷ | 2 |
| = | 212 | × | 1 2 |
| = | 106 | × | 1 |
| x | = | 106 |
