| x | ÷ | ( | 11 2 | − | x | ) | = | 173 10 | ÷ | 51 |
| 方程两边同时乘以: | ( | 11 2 | − | x | ) |
| x | = | 173 10 | ÷ | 51 | × | ( | 11 2 | − | x | ) |
| x | = | 173 10 | ÷ | 51 | × | 11 2 | − | 173 10 | ÷ | 51 | × | x |
| x | = | 1903 1020 | − | 173 510 | x |
| x | + | 173 510 | x | = | 1903 1020 |
683 510 | x | = | 1903 1020 |
| x | = | 1903 1020 | ÷ | 683 510 |
| = | 1903 1020 | × | 510 683 |
| = | 1903 2 | × | 1 683 |
| x | = | 1903 1366 |
| x | = | 1.393119 |
