| ( | 13163 500 | + | x | ) | = | 13163 250 | + | 36389 500 | − | x |
| 方程左边 = | 13163 500 | + | x |
13163 500 | + | x | = | 13163 250 | + | 36389 500 | − | x |
| 方程右边 = | 12543 100 | − | x |
13163 500 | + | x | = | 12543 100 | − | x |
| x | + | x | = | 12543 100 | − | 13163 500 |
| 2 | x | = | 12543 100 | − | 13163 500 |
| 2 | x | = | 12388 125 |
| x | = | 12388 125 | ÷ | 2 |
| = | 12388 125 | × | 1 2 |
| = | 6194 125 | × | 1 |
| x | = | 6194 125 |
