2 | x | ÷ | 3 | − | ( | 2 | x | + | 1 | ) | ÷ | 6 | = | 1 |
方程左边 = | 2 3 | x | − | ( | 2 | x | + | 1 | ) | × | 1 6 |
2 3 | x | − | ( | 2 | x | + | 1 | ) | × | 1 6 | = | 1 |
方程左边 = | 2 3 | x | − | 2 | x | × | 1 6 | − | 1 | × | 1 6 |
= | 2 3 | x | − | 1 3 | x | − | 1 6 |
= | 1 3 | x | − | 1 6 |
1 3 | x | − | 1 6 | = | 1 |
1 3 | x | = | 1 | + | 1 6 |
1 3 | x | = | 7 6 |
x | = | 7 6 | ÷ | 1 3 |
= | 7 6 | × | 3 |
= | 7 2 | × | 1 |
x | = | 7 2 |
x | = | 3.5 |
