| X | ÷ | ( | X | + | 2028 | ) | = | 27 100000 |
| 方程两边同时乘以: | ( | X | + | 2028 | ) |
| X | = | 27 100000 | ( | X | + | 2028 | ) |
| X | = | 27 100000 | X | + | 27 100000 | × | 2028 |
| X | = | 27 100000 | X | + | 13689 25000 |
| X | − | 27 100000 | X | = | 13689 25000 |
99973 100000 | X | = | 13689 25000 |
| X | = | 13689 25000 | ÷ | 99973 100000 |
| = | 13689 25000 | × | 100000 99973 |
| = | 13689 | × | 4 99973 |
| X | = | 54756 99973 |
| X | = | 0.547708 |
