| 方程右边 = | 112167 1000 | − | x |
292523 4000 | + | 7 4 | x | = | 112167 1000 | − | x |
7 4 | x | + | x | = | 112167 1000 | − | 292523 4000 |
11 4 | x | = | 112167 1000 | − | 292523 4000 |
11 4 | x | = | 31229 800 |
| x | = | 31229 800 | ÷ | 11 4 |
| = | 31229 800 | × | 4 11 |
| = | 2839 200 | × | 1 |
