| ( | 376 | ÷ | 5 | ) | x | + | 83 | ( | 1 | − | x | ) | = | 7793 100 |
| 方程左边 = | 376 | ÷ | 5 | × | x | + | 83 | ( | 1 | − | x | ) |
| = | 376 5 | x | + | 83 | ( | 1 | − | x | ) |
| = | 376 5 | x | + | 83 | × | 1 | − | 83 | x |
| = | 376 5 | x | + | 83 | − | 83 | x |
| = | - | 39 5 | x | + | 83 |
| - | 39 5 | x | + | 83 | = | 7793 100 |
| - | 39 5 | x | = | 7793 100 | − | 83 |
| - | 39 5 | x | = | - | 507 100 |
507 100 | = | 39 5 | x |
39 5 | x | = | 507 100 |
| x | = | 507 100 | ÷ | 39 5 |
| = | 507 100 | × | 5 39 |
| = | 13 20 | × | 1 |
| x | = | 13 20 |
| x | = | 0.65 |
