| ( | 43 10 | x | + | 167 10 | ( | 100 | − | x | ) | ) | ÷ | 100 | = | 19 2 |
| 方程左边 = | 43 10 | x | × | 1 100 | + | 167 10 | ( | 100 | − | x | ) | × | 1 100 |
| = | 43 1000 | x | + | 167 1000 | ( | 100 | − | x | ) |
| = | 43 1000 | x | + | 167 1000 | × | 100 | − | 167 1000 | x |
| = | 43 1000 | x | + | 167 10 | − | 167 1000 | x |
| = | - | 31 250 | x | + | 167 10 |
| - | 31 250 | x | + | 167 10 | = | 19 2 |
| - | 31 250 | x | = | 19 2 | − | 167 10 |
| - | 31 250 | x | = | - | 36 5 |
36 5 | = | 31 250 | x |
31 250 | x | = | 36 5 |
| x | = | 36 5 | ÷ | 31 250 |
| = | 36 5 | × | 250 31 |
| = | 36 | × | 50 31 |
| x | = | 1800 31 |
