| 218 | x | − | 10283 50 | x | × | 1 4 | − | 76 | x | = | ( | 22 | − | x | ) | × | 50 |
| 方程左边 = | 218 | x | − | 10283 200 | x | − | 76 | x |
| = | 18117 200 | x |
18117 200 | x | = | ( | 22 | − | x | ) | × | 50 |
| 方程右边 = | 22 | × | 50 | − | x | × | 50 |
| = | 1100 | − | x | × | 50 |
18117 200 | x | = | 1100 | − | 50 | x |
18117 200 | x | + | 50 | x | = | 1100 |
28117 200 | x | = | 1100 |
| x | = | 1100 | ÷ | 28117 200 |
| = | 1100 | × | 200 28117 |
| x | = | 220000 28117 |
| x | = | 7.824448 |
