| 方程左边 = | 479 | × | 24 5 | + | x | × | 24 5 |
| = | 11496 5 | + | x | × | 24 5 |
11496 5 | + | 24 5 | x | = | 5 | x | + | 471 | × | 23 5 |
| 方程右边 = | 5 | x | + | 10833 5 |
11496 5 | + | 24 5 | x | = | 5 | x | + | 10833 5 |
24 5 | x | − | 5 | x | = | 10833 5 | − | 11496 5 |
| - | 1 5 | x | = | 10833 5 | − | 11496 5 |
| - | 1 5 | x | = | - | 663 5 |
663 5 | = | 1 5 | x |
1 5 | x | = | 663 5 |
| x | = | 663 5 | ÷ | 1 5 |
| = | 663 5 | × | 5 |
