| 方程左边 = | 3 2 | × | 2 | ( | X | − | 2 | ÷ | 1 | ) | + | 3 2 | × | 3 | ÷ | 2 |
| = | 3 | ( | X | − | 2 | ÷ | 1 | ) | + | 9 4 |
| = | 3 | X | − | 3 | × | 2 | ÷ | 1 | + | 9 4 |
| = | 3 | X | − | 6 | + | 9 4 |
| = | 3 | X | − | 15 4 |
| 3 | X | − | 15 4 | = | 6 | X |
| 3 | X | − | 6 | X | = | 15 4 |
| - | 3 | X | = | 15 4 |
| - | 15 4 | = | 3 | X |
| 3 | X | = | - | 15 4 |
| X | = | - | 15 4 | ÷ | 3 |
| = | - | 15 4 | × | 1 3 |
| = | - | 5 4 | × | 1 |
| X | = | - | 5 4 |
