| x | ÷ | 10 | + | ( | 14 | − | x | ) | × | 15 | = | 1 |
| 方程左边 = | 1 10 | x | + | 14 | × | 15 | − | x | × | 15 |
| = | 1 10 | x | + | 210 | − | x | × | 15 |
| = | - | 149 10 | x | + | 210 |
| - | 149 10 | x | + | 210 | = | 1 |
| - | 149 10 | x | = | 1 | − | 210 |
| - | 149 10 | x | = | - | 209 |
| 209 | = | 149 10 | x |
149 10 | x | = | 209 |
| x | = | 209 | ÷ | 149 10 |
| = | 209 | × | 10 149 |
| x | = | 2090 149 |
| x | = | 14.026846 |
