| ( | 5 | x | − | 2 | ) | ÷ | ( | 2 | x | + | 2 | ) | = | 4 | ÷ | 3 |
| 方程两边同时乘以: | ( | 2 | x | + | 2 | ) |
| ( | 5 | x | − | 2 | ) | = | 4 | ÷ | 3 | × | ( | 2 | x | + | 2 | ) |
| 5 | x | − | 2 | = | 4 | ÷ | 3 | × | ( | 2 | x | + | 2 | ) |
| 5 | x | − | 2 | = | 4 | ÷ | 3 | × | 2 | x | + | 4 | ÷ | 3 | × | 2 |
| 5 | x | − | 2 | = | 8 3 | x | + | 8 3 |
| 5 | x | − | 8 3 | x | = | 8 3 | + | 2 |
7 3 | x | = | 8 3 | + | 2 |
7 3 | x | = | 14 3 |
| x | = | 14 3 | ÷ | 7 3 |
| = | 14 3 | × | 3 7 |
| = | 2 | × | 1 |
| x | = | 2 |
