| x | ÷ | ( | 11 2 | − | x | ) | = | 156 5 | ÷ | 51 |
| 方程两边同时乘以: | ( | 11 2 | − | x | ) |
| x | = | 156 5 | ÷ | 51 | × | ( | 11 2 | − | x | ) |
| x | = | 156 5 | ÷ | 51 | × | 11 2 | − | 156 5 | ÷ | 51 | × | x |
| x | = | 286 85 | − | 52 85 | x |
| x | + | 52 85 | x | = | 286 85 |
137 85 | x | = | 286 85 |
| x | = | 286 85 | ÷ | 137 85 |
| = | 286 85 | × | 85 137 |
| = | 286 | × | 1 137 |
| x | = | 286 137 |
| x | = | 2.087591 |
