| 方程右边 = | 58 | × | 121 5 | − | x | × | 121 5 | + | 79 5 | x |
| = | 7018 5 | − | x | × | 121 5 | + | 79 5 | x |
| = | 7018 5 | − | 42 5 | x |
6057 5 | = | 7018 5 | − | 42 5 | x |
42 5 | x | = | 7018 5 | − | 6057 5 |
42 5 | x | = | 961 5 |
| x | = | 961 5 | ÷ | 42 5 |
| = | 961 5 | × | 5 42 |
| = | 961 | × | 1 42 |
| x | = | 961 42 |
