方程两边同时乘以: | ( | 5000 | + | x | ) |
26 5 | ( | 5000 | + | x | ) | = | ( | 29000 | + | 29 5 | x | ) |
26 5 | × | 5000 | + | 26 5 | x | = | ( | 29000 | + | 29 5 | x | ) |
26 5 | × | 5000 | + | 26 5 | x | = | 29000 | + | 29 5 | x |
26000 | + | 26 5 | x | = | 29000 | + | 29 5 | x |
26 5 | x | − | 29 5 | x | = | 29000 | − | 26000 |
- | 3 5 | x | = | 29000 | − | 26000 |
- | 3 5 | x | = | 3000 |
- | 3000 | = | 3 5 | x |
3 5 | x | = | - | 3000 |
x | = | - | 3000 | ÷ | 3 5 |
= | - | 3000 | × | 5 3 |
= | - | 1000 | × | 5 |
