| ( | 1150 | − | X | ) | ÷ | 1150 | = | 2083 10000 |
| 方程左边 = | 1150 | × | 1 1150 | − | X | × | 1 1150 |
| = | 1 | − | X | × | 1 1150 |
| 1 | − | 1 1150 | X | = | 2083 10000 |
| - | 1 1150 | X | = | 2083 10000 | − | 1 |
| - | 1 1150 | X | = | - | 7917 10000 |
7917 10000 | = | 1 1150 | X |
1 1150 | X | = | 7917 10000 |
| X | = | 7917 10000 | ÷ | 1 1150 |
| = | 7917 10000 | × | 1150 |
| = | 7917 200 | × | 23 |
