| ( | 1310 | − | 150 | x | ) | ÷ | 150 | + | 150 | x | = | 1310 | × | 2 |
| 方程左边 = | 1310 | × | 1 150 | − | 150 | x | × | 1 150 | + | 150 | x |
| = | 131 15 | − | 1 | x | + | 150 | x |
| = | 131 15 | + | 149 | x |
131 15 | + | 149 | x | = | 1310 | × | 2 |
| 方程右边 = | 2620 |
131 15 | + | 149 | x | = | 2620 |
| 149 | x | = | 2620 | − | 131 15 |
| 149 | x | = | 39169 15 |
| x | = | 39169 15 | ÷ | 149 |
| = | 39169 15 | × | 1 149 |
| x | = | 39169 2235 |
| x | = | 17.52528 |
