| 方程右边 = | 129 100 | ( | 1 | + | g | ) | × | 1 5 | + | g |
| = | 129 500 | ( | 1 | + | g | ) | + | g |
| = | 129 500 | × | 1 | + | 129 500 | g | + | g |
| = | 129 500 | + | 129 500 | g | + | g |
| = | 129 500 | + | 629 500 | g |
2469 10000 | = | 129 500 | + | 629 500 | g |
| - | 629 500 | g | = | 129 500 | − | 2469 10000 |
| - | 629 500 | g | = | 111 10000 |
| - | 111 10000 | = | 629 500 | g |
629 500 | g | = | - | 111 10000 |
| g | = | - | 111 10000 | ÷ | 629 500 |
| = | - | 111 10000 | × | 500 629 |
| = | - | 111 20 | × | 1 629 |
