( | ( | 24 | + | x | ) | ÷ | 3 | ) | − | ( | ( | 4 | x | + | 8 | ) | ÷ | 3 | ) | = | 5 |
方程左边 = | ( | 24 | + | x | ) | ÷ | 3 | − | ( | ( | 4 | x | + | 8 | ) | ÷ | 3 | ) |
= | 24 | × | 1 3 | + | x | × | 1 3 | − | ( | ( | 4 | x | + | 8 | ) | ÷ | 3 | ) |
= | 8 | + | x | × | 1 3 | − | ( | ( | 4 | x | + | 8 | ) | ÷ | 3 | ) |
= | 8 | + | 1 3 | x | − | ( | 4 | x | + | 8 | ) | ÷ | 3 |
= | 8 | + | 1 3 | x | − | 4 | x | × | 1 3 | − | 8 | × | 1 3 |
= | 8 | + | 1 3 | x | − | 4 3 | x | − | 8 3 |
= | 16 3 | − | 1 | x |
16 3 | − | 1 | x | = | 5 |
- | 1 | x | = | 5 | − | 16 3 |
- | x | = | 5 | − | 16 3 |
- | x | = | - | 1 3 |
1 3 | = | x |
x | = | 1 3 |
