6 5 | ( | 4 | + | x | ) | = | 18 5 | ( | x | − | 14 | ) |
方程左边 = | 6 5 | × | 4 | + | 6 5 | x |
= | 24 5 | + | 6 5 | x |
24 5 | + | 6 5 | x | = | 18 5 | ( | x | − | 14 | ) |
方程右边 = | 18 5 | x | − | 18 5 | × | 14 |
= | 18 5 | x | − | 252 5 |
24 5 | + | 6 5 | x | = | 18 5 | x | − | 252 5 |
6 5 | x | − | 18 5 | x | = | - | 252 5 | − | 24 5 |
- | 12 5 | x | = | - | 252 5 | − | 24 5 |
- | 12 5 | x | = | - | 276 5 |
276 5 | = | 12 5 | x |
12 5 | x | = | 276 5 |
x | = | 276 5 | ÷ | 12 5 |
= | 276 5 | × | 5 12 |
= | 23 | × | 1 |
x | = | 23 |
