| 196 | − | x | = | ( | 181 | ÷ | 3 | ) | + | ( | 1 | ÷ | 3 | ) | x |
| 方程右边 = | 181 | ÷ | 3 | + | ( | 1 | ÷ | 3 | ) | x |
| = | 181 3 | + | ( | 1 | ÷ | 3 | ) | x |
| = | 181 3 | + | 1 | ÷ | 3 | × | x |
| = | 181 3 | + | 1 3 | x |
| 196 | − | x | = | 181 3 | + | 1 3 | x |
| - | x | − | 1 3 | x | = | 181 3 | − | 196 |
| - | 4 3 | x | = | 181 3 | − | 196 |
| - | 4 3 | x | = | - | 407 3 |
407 3 | = | 4 3 | x |
4 3 | x | = | 407 3 |
| x | = | 407 3 | ÷ | 4 3 |
| = | 407 3 | × | 3 4 |
| = | 407 | × | 1 4 |
| x | = | 407 4 |
| x | = | 101.75 |
