| x | = | 2 125 | ÷ | ( | 241 100 | − | 141 100 | × | 2 125 | ) |
| 方程两边同时乘以: | ( | 241 100 | − | 141 100 | × | 2 125 | ) |
| x | ( | 241 100 | − | 141 100 | × | 2 125 | ) | = | 2 125 |
| x | × | 241 100 | − | x | × | 141 100 | × | 2 125 | = | 2 125 |
| x | × | 241 100 | − | x | × | 141 6250 | = | 2 125 |
