| ( | x | + | 35 | ( | 1 | − | x | ) | ) | × | 6 | = | 128 |
| 方程左边 = | x | × | 6 | + | 35 | ( | 1 | − | x | ) | × | 6 |
| = | x | × | 6 | + | 210 | ( | 1 | − | x | ) |
| = | 6 | x | + | 210 | × | 1 | − | 210 | x |
| = | 6 | x | + | 210 | − | 210 | x |
| = | - | 204 | x | + | 210 |
| - | 204 | x | + | 210 | = | 128 |
| - | 204 | x | = | 128 | − | 210 |
| - | 204 | x | = | - | 82 |
| 82 | = | 204 | x |
| 204 | x | = | 82 |
| x | = | 82 | ÷ | 204 |
| = | 82 | × | 1 204 |
| = | 41 | × | 1 102 |
| x | = | 41 102 |
| x | = | 0.401961 |
