| ( | X | − | 3373933039 50 | ) | ÷ | X | = | 1 100 |
| 方程两边同时乘以: | X |
| ( | X | − | 3373933039 50 | ) | = | 1 100 | X |
| X | − | 3373933039 50 | = | 1 100 | X |
| X | − | 1 100 | X | = | 3373933039 50 |
99 100 | X | = | 3373933039 50 |
| X | = | 3373933039 50 | ÷ | 99 100 |
| = | 3373933039 50 | × | 100 99 |
| = | 3373933039 | × | 2 99 |
