| 65 | ÷ | 95 | + | x | = | 95 | + | x | ÷ | 160 | + | x |
| 方程左边 = | 13 19 | + | x |
13 19 | + | x | = | 95 | + | x | ÷ | 160 | + | x |
| 方程右边 = | 95 | + | 161 160 | x |
13 19 | + | x | = | 95 | + | 161 160 | x |
| x | − | 161 160 | x | = | 95 | − | 13 19 |
| - | 1 160 | x | = | 95 | − | 13 19 |
| - | 1 160 | x | = | 1792 19 |
| - | 1792 19 | = | 1 160 | x |
1 160 | x | = | - | 1792 19 |
| x | = | - | 1792 19 | ÷ | 1 160 |
| = | - | 1792 19 | × | 160 |
