方程左边 = | 622 5 | + | 22 | × | 43 10 | − | x | × | 43 10 |
= | 622 5 | + | 473 5 | − | x | × | 43 10 |
= | 219 | − | 43 10 | x |
219 | − | 43 10 | x | = | ( | 50 | + | 446 5 | + | 13 2 | x | ) | ÷ | 3 2 |

= | 100 3 | + | 892 15 | + | 13 3 | x |
= | 464 5 | + | 13 3 | x |
219 | − | 43 10 | x | = | 464 5 | + | 13 3 | x |
- | 43 10 | x | − | 13 3 | x | = | 464 5 | − | 219 |
- | 259 30 | x | = | 464 5 | − | 219 |
- | 259 30 | x | = | - | 631 5 |
631 5 | = | 259 30 | x |
259 30 | x | = | 631 5 |
x | = | 631 5 | ÷ | 259 30 |
= | 631 5 | × | 30 259 |
= | 631 | × | 6 259 |
