| ( | x | + | ( | ( | 1 | − | x | ) | × | 1 2 | ) | ÷ | 100 | ) | = | 9741 10000 |
| 方程左边 = | x | + | ( | ( | 1 | − | x | ) | × | 1 2 | ) | ÷ | 100 |
| = | x | + | ( | 1 | − | x | ) | × | 1 2 | × | 1 100 |
| = | x | + | ( | 1 | − | x | ) | × | 1 200 |
| = | x | + | 1 | × | 1 200 | − | x | × | 1 200 |
| = | x | + | 1 200 | − | x | × | 1 200 |
| = | 199 200 | x | + | 1 200 |
199 200 | x | + | 1 200 | = | 9741 10000 |
199 200 | x | = | 9741 10000 | − | 1 200 |
199 200 | x | = | 9691 10000 |
| x | = | 9691 10000 | ÷ | 199 200 |
| = | 9691 10000 | × | 200 199 |
| = | 9691 50 | × | 1 199 |
| x | = | 9691 9950 |
| x | = | 0.97397 |
