| x | ÷ | ( | 2600 | + | x | ) | = | 53 1000 |
| 方程两边同时乘以: | ( | 2600 | + | x | ) |
| x | = | 53 1000 | ( | 2600 | + | x | ) |
| x | = | 53 1000 | × | 2600 | + | 53 1000 | x |
| x | = | 689 5 | + | 53 1000 | x |
| x | − | 53 1000 | x | = | 689 5 |
947 1000 | x | = | 689 5 |
| x | = | 689 5 | ÷ | 947 1000 |
| = | 689 5 | × | 1000 947 |
| = | 689 | × | 200 947 |
| x | = | 137800 947 |
| x | = | 145.512144 |
