3 | ÷ | 4 | × | ( | 4 | ÷ | 3 | × | ( | 1 | ÷ | 2 | × | x | − | 1 | ) | + | 8 | ) | = | 3 | ÷ | 2 | × | x | + | 1 |
方程左边 = | 3 4 | ( | 4 | ÷ | 3 | × | ( | 1 | ÷ | 2 | × | x | − | 1 | ) | + | 8 | ) |
3 4 | ( | 4 | ÷ | 3 | × | ( | 1 | ÷ | 2 | × | x | − | 1 | ) | + | 8 | ) | = | 3 | ÷ | 2 | × | x | + | 1 |
方程左边 = | 3 4 | × | 4 | ÷ | 3 | × | ( | 1 | ÷ | 2 | × | x | − | 1 | ) | + | 3 4 | × | 8 |
= | 1 | ( | 1 | ÷ | 2 | × | x | − | 1 | ) | + | 6 |
= | 1 | × | 1 | ÷ | 2 | × | x | − | 1 | × | 1 | + | 6 |
= | 1 2 | x | − | 1 | + | 6 |
= | 1 2 | x | + | 5 |
1 2 | x | + | 5 | = | 3 | ÷ | 2 | × | x | + | 1 |
方程右边 = | 3 2 | x | + | 1 |
1 2 | x | + | 5 | = | 3 2 | x | + | 1 |
1 2 | x | − | 3 2 | x | = | 1 | − | 5 |
- | x | = | 1 | − | 5 |
- | x | = | 1 | − | 5 |
- | x | = | - | 4 |
4 | = | x |
x | = | 4 |
