| 100000 | ÷ | 5 | + | 3 5 | x | × | 10 | = | 190000 | ÷ | 5 | + | 3 10 |
| 方程左边 = | 20000 | + | 6 | x |
| 20000 | + | 6 | x | = | 190000 | ÷ | 5 | + | 3 10 |
| 方程右边 = | 38000 | + | 3 10 |
| = | 380003 10 |
| 20000 | + | 6 | x | = | 380003 10 |
| 6 | x | = | 380003 10 | − | 20000 |
| 6 | x | = | 180003 10 |
| x | = | 180003 10 | ÷ | 6 |
| = | 180003 10 | × | 1 6 |
| = | 60001 10 | × | 1 2 |
| x | = | 60001 20 |
| x | = | 3000.05 |
