| 方程右边 = | 1413 50 | x | − | 1413 50 | × | 14 |
| = | 1413 50 | x | − | 9891 25 |
157 50 | x | − | 157 5 | = | 1413 50 | x | − | 9891 25 |
157 50 | x | − | 1413 50 | x | = | - | 9891 25 | + | 157 5 |
| - | 628 25 | x | = | - | 9891 25 | + | 157 5 |
| - | 628 25 | x | = | - | 9106 25 |
9106 25 | = | 628 25 | x |
628 25 | x | = | 9106 25 |
| x | = | 9106 25 | ÷ | 628 25 |
| = | 9106 25 | × | 25 628 |
