11 10 | x | + | 3991 50 | = | 93 10 | ( | x | + | 1 | ) |
| 方程右边 = | 93 10 | x | + | 93 10 | × | 1 |
| = | 93 10 | x | + | 93 10 |
11 10 | x | + | 3991 50 | = | 93 10 | x | + | 93 10 |
11 10 | x | − | 93 10 | x | = | 93 10 | − | 3991 50 |
| - | 41 5 | x | = | 93 10 | − | 3991 50 |
| - | 41 5 | x | = | - | 1763 25 |
1763 25 | = | 41 5 | x |
41 5 | x | = | 1763 25 |
| x | = | 1763 25 | ÷ | 41 5 |
| = | 1763 25 | × | 5 41 |
| = | 43 5 | × | 1 |
| x | = | 43 5 |
