| 方程左边 = | 1 4 | × | 1000 | + | 1 4 | x |
| = | 250 | + | 1 4 | x |
| 250 | + | 1 4 | x | = | 53 250 | × | 1000 | + | 1121 1000 | x |
| 方程右边 = | 212 | + | 1121 1000 | x |
| 250 | + | 1 4 | x | = | 212 | + | 1121 1000 | x |
1 4 | x | − | 1121 1000 | x | = | 212 | − | 250 |
| - | 871 1000 | x | = | 212 | − | 250 |
| - | 871 1000 | x | = | - | 38 |
| 38 | = | 871 1000 | x |
871 1000 | x | = | 38 |
| x | = | 38 | ÷ | 871 1000 |
| = | 38 | × | 1000 871 |
| x | = | 38000 871 |
| x | = | 43.628014 |
