| ( | x | − | 884231 100 | ) | ÷ | ( | x | ÷ | 13 100 | ) | = | 1 250 |
| 方程两边同时乘以: | ( | x | ÷ | 13 100 | ) |
| ( | x | − | 884231 100 | ) | = | 1 250 | ( | x | ÷ | 13 100 | ) |
| x | − | 884231 100 | = | 1 250 | ( | x | ÷ | 13 100 | ) |
| x | − | 884231 100 | = | 1 250 | x | ÷ | 13 100 |
| x | − | 884231 100 | = | 2 65 | x |
| x | − | 2 65 | x | = | 884231 100 |
63 65 | x | = | 884231 100 |
| x | = | 884231 100 | ÷ | 63 65 |
| = | 884231 100 | × | 65 63 |
| = | 884231 20 | × | 13 63 |
