| x | ÷ | 109 100 | + | ( | 94 | − | x | ) | ÷ | 113 100 | = | 84 |
| 方程左边 = | 100 109 | x | + | 94 | × | 100 113 | − | x | × | 100 113 |
| = | 100 109 | x | + | 9400 113 | − | x | × | 100 113 |
| = | 400 12317 | x | + | 9400 113 |
400 12317 | x | + | 9400 113 | = | 84 |
400 12317 | x | = | 84 | − | 9400 113 |
400 12317 | x | = | 92 113 |
| x | = | 92 113 | ÷ | 400 12317 |
| = | 92 113 | × | 12317 400 |
| = | 23 113 | × | 12317 100 |
