300000 | ÷ | x | = | 300000 | ÷ | ( | x | + | 1000 | ) | + | 10 |
方程两边同时乘以: | x | , | ( | x | + | 1000 | ) |
300000 | ( | x | + | 1000 | ) | = | 300000 | x | + | 10 | x | ( | x | + | 1000 | ) |
300000 | x | + | 300000 | × | 1000 | = | 300000 | x | + | 10 | x | ( | x | + | 1000 | ) |
300000 | x | + | 300000 | × | 1000 | = | 300000 | x | + | 10 | x | x | + | 10 | x | × | 1000 |
300000 | x | + | 300000000 | = | 300000 | x | + | 10 | x | x | + | 10000 | x |
300000 | x | + | 300000000 | = | 310000 | x | + | 10 | x | x |
