| 方程右边 = | 97571 1000 | − | x |
236637 4000 | + | 9 4 | x | = | 97571 1000 | − | x |
9 4 | x | + | x | = | 97571 1000 | − | 236637 4000 |
13 4 | x | = | 97571 1000 | − | 236637 4000 |
13 4 | x | = | 153647 4000 |
| x | = | 153647 4000 | ÷ | 13 4 |
| = | 153647 4000 | × | 4 13 |
| = | 11819 1000 | × | 1 |
