| 5 | ( | x | − | 24 | ) | = | ( | 150 | − | x | ) | ÷ | 18 25 |
| 方程左边 = | 5 | x | − | 5 | × | 24 |
| = | 5 | x | − | 120 |
| 5 | x | − | 120 | = | ( | 150 | − | x | ) | ÷ | 18 25 |
| 方程右边 = | 150 | × | 25 18 | − | x | × | 25 18 |
| = | 625 3 | − | x | × | 25 18 |
| 5 | x | − | 120 | = | 625 3 | − | 25 18 | x |
| 5 | x | + | 25 18 | x | = | 625 3 | + | 120 |
115 18 | x | = | 625 3 | + | 120 |
115 18 | x | = | 985 3 |
| x | = | 985 3 | ÷ | 115 18 |
| = | 985 3 | × | 18 115 |
| = | 197 | × | 6 23 |
| x | = | 1182 23 |
| x | = | 51.391304 |
