| ( | 2000 | X | ) | ÷ | ( | 10000 | + | 480 | ) | = | 160 100 |
| 方程两边同时乘以: | ( | 10000 | + | 480 | ) |
| ( | 2000 | X | ) | = | 160 100 | ( | 10000 | + | 480 | ) |
| 2000 | X | = | 160 100 | ( | 10000 | + | 480 | ) |
| 2000 | X | = | 160 100 | × | 10000 | + | 160 100 | × | 480 |
| 2000 | X | = | 16000 | + | 768 |
| 2000 | X | = | 16768 |
| X | = | 16768 | ÷ | 2000 |
| = | 16768 | × | 1 2000 |
| = | 1048 | × | 1 125 |
| X | = | 1048 125 |
| X | = | 8.384 |
