| ( | 2 | x | − | 3 | ) | × | 2 | + | 2 | = | 3 | ( | 2 | x | − | 3 | ) |
| 方程左边 = | 2 | x | × | 2 | − | 3 | × | 2 | + | 2 |
| = | 4 | x | − | 6 | + | 2 |
| = | 4 | x | − | 4 |
| 4 | x | − | 4 | = | 3 | ( | 2 | x | − | 3 | ) |
| 方程右边 = | 3 | × | 2 | x | − | 3 | × | 3 |
| = | 6 | x | − | 9 |
| 4 | x | − | 4 | = | 6 | x | − | 9 |
| 4 | x | − | 6 | x | = | - | 9 | + | 4 |
| - | 2 | x | = | - | 9 | + | 4 |
| - | 2 | x | = | - | 5 |
| 5 | = | 2 | x |
| 2 | x | = | 5 |
| x | = | 5 | ÷ | 2 |
| = | 5 | × | 1 2 |
| x | = | 5 2 |
| x | = | 2.5 |
