| 方程两边同时乘以: | ( | 13 | ÷ | 100 | ) |
| x | = | 54498 | ( | 13 | ÷ | 100 | ) | − | x | ( | 13 | ÷ | 100 | ) |
| x | = | 54498 | × | 13 | ÷ | 100 | − | x | ( | 13 | ÷ | 100 | ) |
| x | = | 354237 50 | − | x | ( | 13 | ÷ | 100 | ) |
| x | = | 354237 50 | − | x | × | 13 | ÷ | 100 |
| x | = | 354237 50 | − | x | × | 13 100 |
| x | + | 13 100 | x | = | 354237 50 |
113 100 | x | = | 354237 50 |
| x | = | 354237 50 | ÷ | 113 100 |
| = | 354237 50 | × | 100 113 |
| = | 354237 | × | 2 113 |
