| 方程右边 = | 1193 25 | × | 1 500 | − | x | × | 1 500 | + | 1299 5000 |
| = | 1193 12500 | − | x | × | 1 500 | + | 1299 5000 |
| = | 8881 25000 | − | 1 500 | x |
4 555 | x | = | 8881 25000 | − | 1 500 | x |
4 555 | x | + | 1 500 | x | = | 8881 25000 |
511 55500 | x | = | 8881 25000 |
| x | = | 8881 25000 | ÷ | 511 55500 |
| = | 8881 25000 | × | 55500 511 |
| = | 8881 50 | × | 111 511 |
| x | = | 985791 25550 |
