7 | x | ( | 1 | ÷ | 3 | ) | = | ( | 4 | x | − | 1 | ) | ( | 1 | ÷ | 6 | ) | + | 1 |
方程左边 = | 7 | x | × | 1 | ÷ | 3 |
= | 7 3 | x |
7 3 | x | = | ( | 4 | x | − | 1 | ) | ( | 1 | ÷ | 6 | ) | + | 1 |
方程右边 = | 4 | x | ( | 1 | ÷ | 6 | ) | − | 1 | ( | 1 | ÷ | 6 | ) | + | 1 |
= | 4 | x | × | 1 | ÷ | 6 | − | 1 | ( | 1 | ÷ | 6 | ) | + | 1 |
= | 2 3 | x | − | 1 | ( | 1 | ÷ | 6 | ) | + | 1 |
= | 2 3 | x | − | 1 | × | 1 | ÷ | 6 | + | 1 |
= | 2 3 | x | − | 1 6 | + | 1 |
= | 2 3 | x | + | 5 6 |
7 3 | x | = | 2 3 | x | + | 5 6 |
7 3 | x | − | 2 3 | x | = | 5 6 |
5 3 | x | = | 5 6 |
x | = | 5 6 | ÷ | 5 3 |
= | 5 6 | × | 3 5 |
= | 1 2 | × | 1 |
x | = | 1 2 |
x | = | 0.5 |
