| ( | ( | x | − | 99 | ) | ÷ | 99 | ) | ( | 360 | ÷ | 180 | ) | = | 6 100 |
| 方程左边 = | ( | x | − | 99 | ) | ÷ | 99 | × | ( | 360 | ÷ | 180 | ) |
| = | x | × | 1 99 | ( | 360 | ÷ | 180 | ) | − | 99 | × | 1 99 | ( | 360 | ÷ | 180 | ) |
| = | x | × | 1 99 | ( | 360 | ÷ | 180 | ) | − | 1 | ( | 360 | ÷ | 180 | ) |
| = | x | × | 1 99 | × | 360 | ÷ | 180 | − | 1 | ( | 360 | ÷ | 180 | ) |
| = | x | × | 2 99 | − | 1 | ( | 360 | ÷ | 180 | ) |
| = | 2 99 | x | − | 1 | × | 360 | ÷ | 180 |
| = | 2 99 | x | − | 2 |
2 99 | x | − | 2 | = | 6 100 |
2 99 | x | = | 6 100 | + | 2 |
2 99 | x | = | 103 50 |
| x | = | 103 50 | ÷ | 2 99 |
| = | 103 50 | × | 99 2 |
| x | = | 10197 100 |
| x | = | 101.97 |
