| ( | x | + | 943 10 | ) | ÷ | 49 50 | = | ( | x | ÷ | 9 10 | ) | + | 9581 100 |
| 方程左边 = | x | × | 50 49 | + | 943 10 | × | 50 49 |
| = | x | × | 50 49 | + | 4715 49 |
50 49 | x | + | 4715 49 | = | ( | x | ÷ | 9 10 | ) | + | 9581 100 |
| 方程右边 = | x | ÷ | 9 10 | + | 9581 100 |
50 49 | x | + | 4715 49 | = | 10 9 | x | + | 9581 100 |
50 49 | x | − | 10 9 | x | = | 9581 100 | − | 4715 49 |
| - | 40 441 | x | = | 9581 100 | − | 4715 49 |
| - | 40 441 | x | = | - | 2031 4900 |
2031 4900 | = | 40 441 | x |
40 441 | x | = | 2031 4900 |
| x | = | 2031 4900 | ÷ | 40 441 |
| = | 2031 4900 | × | 441 40 |
| = | 2031 100 | × | 9 40 |
