方程两边同时乘以: | ( | 200 | + | x | ) |
53 2000 | ( | 200 | + | x | ) | = | x |
53 2000 | × | 200 | + | 53 2000 | x | = | x |
53 10 | + | 53 2000 | x | = | x |
53 2000 | x | − | x | = | - | 53 10 |
- | 1947 2000 | x | = | - | 53 10 |
53 10 | = | 1947 2000 | x |
1947 2000 | x | = | 53 10 |
x | = | 53 10 | ÷ | 1947 2000 |
= | 53 10 | × | 2000 1947 |
= | 53 | × | 200 1947 |
x | = | 10600 1947 |
