| x | ÷ | 4 | + | 1 | = | ( | 3 | x | + | 1 | ) | ÷ | 1 10 | + | 6 5 |
| 方程右边 = | 3 | x | × | 10 | + | 1 | × | 10 | + | 6 5 |
| = | 30 | x | + | 10 | + | 6 5 |
| = | 30 | x | + | 56 5 |
1 4 | x | + | 1 | = | 30 | x | + | 56 5 |
1 4 | x | − | 30 | x | = | 56 5 | − | 1 |
| - | 119 4 | x | = | 56 5 | − | 1 |
| - | 119 4 | x | = | 51 5 |
| - | 51 5 | = | 119 4 | x |
119 4 | x | = | - | 51 5 |
| x | = | - | 51 5 | ÷ | 119 4 |
| = | - | 51 5 | × | 4 119 |
| = | - | 3 5 | × | 4 7 |
