| x | − | ( | 83 | + | 74 | + | 71 | + | 64 | + | x | ) | ÷ | 5 | = | 32 |
| 方程左边 = | x | − | 83 | × | 1 5 | − | 74 | × | 1 5 | − | 71 | × | 1 5 | − | 64 | × | 1 5 | − | x | × | 1 5 |
| = | x | − | 83 5 | − | 74 5 | − | 71 5 | − | 64 5 | − | x | × | 1 5 |
| = | 4 5 | x | − | 292 5 |
4 5 | x | − | 292 5 | = | 32 |
4 5 | x | = | 32 | + | 292 5 |
4 5 | x | = | 452 5 |
| x | = | 452 5 | ÷ | 4 5 |
| = | 452 5 | × | 5 4 |
| = | 113 | × | 1 |
| x | = | 113 |
