| ( | 10 | x | + | 3182 5 | ) | ÷ | ( | x | + | 86 | ) | = | 8 |
| 方程两边同时乘以: | ( | x | + | 86 | ) |
| ( | 10 | x | + | 3182 5 | ) | = | 8 | ( | x | + | 86 | ) |
| 10 | x | + | 3182 5 | = | 8 | ( | x | + | 86 | ) |
| 10 | x | + | 3182 5 | = | 8 | x | + | 8 | × | 86 |
| 10 | x | + | 3182 5 | = | 8 | x | + | 688 |
| 10 | x | − | 8 | x | = | 688 | − | 3182 5 |
| 2 | x | = | 688 | − | 3182 5 |
| 2 | x | = | 258 5 |
| x | = | 258 5 | ÷ | 2 |
| = | 258 5 | × | 1 2 |
| = | 129 5 | × | 1 |
| x | = | 129 5 |
| x | = | 25.8 |
