| 14 | = | 241 200 | × | 1 | + | 241 200 | × | 220 | ÷ | x |
| 14 | = | 241 200 | + | 2651 10 | ÷ | x |
| 方程两边同时乘以: | x |
| 14 | x | = | 241 200 | x | + | 2651 10 |
| 14 | x | − | 241 200 | x | = | 2651 10 |
2559 200 | x | = | 2651 10 |
| x | = | 2651 10 | ÷ | 2559 200 |
| = | 2651 10 | × | 200 2559 |
| = | 2651 | × | 20 2559 |
| x | = | 53020 2559 |
