| 16 | ÷ | 25 | − | 3 10 | ( | x | + | 1 5 | ) | = | 1 10 | x |
| 方程左边 = | 16 25 | − | 3 10 | ( | x | + | 1 5 | ) |
16 25 | − | 3 10 | ( | x | + | 1 5 | ) | = | 1 10 | x |
| 方程左边 = | 16 25 | − | 3 10 | x | − | 3 10 | × | 1 5 |
| = | 16 25 | − | 3 10 | x | − | 3 50 |
| = | 29 50 | − | 3 10 | x |
29 50 | − | 3 10 | x | = | 1 10 | x |
| - | 3 10 | x | − | 1 10 | x | = | - | 29 50 |
| - | 2 5 | x | = | - | 29 50 |
29 50 | = | 2 5 | x |
2 5 | x | = | 29 50 |
| x | = | 29 50 | ÷ | 2 5 |
| = | 29 50 | × | 5 2 |
| = | 29 10 | × | 1 2 |
| x | = | 29 20 |
| x | = | 1.45 |
