| ( | 852 | + | x | ) | ÷ | ( | 2367 | + | x | ) | = | 9 25 |
| 方程两边同时乘以: | ( | 2367 | + | x | ) |
| ( | 852 | + | x | ) | = | 9 25 | ( | 2367 | + | x | ) |
| 852 | + | x | = | 9 25 | ( | 2367 | + | x | ) |
| 852 | + | x | = | 9 25 | × | 2367 | + | 9 25 | x |
| 852 | + | x | = | 21303 25 | + | 9 25 | x |
| x | − | 9 25 | x | = | 21303 25 | − | 852 |
16 25 | x | = | 21303 25 | − | 852 |
16 25 | x | = | 3 25 |
| x | = | 3 25 | ÷ | 16 25 |
| = | 3 25 | × | 25 16 |
| = | 3 | × | 1 16 |
| x | = | 3 16 |
| x | = | 0.1875 |
