( | 1 | ÷ | 12 | ) | + | ( | 1 | ÷ | 2 | × | x | ) | = | 1 | ÷ | 2 |
方程左边 = | 1 | ÷ | 12 | + | ( | 1 | ÷ | 2 | × | x | ) |
= | 1 12 | + | ( | 1 | ÷ | 2 | × | x | ) |
= | 1 12 | + | 1 | ÷ | 2 | × | x |
= | 1 12 | + | 1 2 | x |
1 12 | + | 1 2 | x | = | 1 | ÷ | 2 |
方程右边 = | 1 2 |
1 12 | + | 1 2 | x | = | 1 2 |
1 2 | x | = | 1 2 | − | 1 12 |
1 2 | x | = | 5 12 |
x | = | 5 12 | ÷ | 1 2 |
= | 5 12 | × | 2 |
= | 5 6 | × | 1 |
x | = | 5 6 |
x | = | 0.833333 |
