14 | + | ( | 1 | ÷ | 4 | ) | x | − | 2 | = | ( | 4 | ÷ | 3 | ) | x | + | 2 |
方程左边 = | 12 | + | ( | 1 | ÷ | 4 | ) | x |
12 | + | ( | 1 | ÷ | 4 | ) | x | = | ( | 4 | ÷ | 3 | ) | x | + | 2 |
方程左边 = | 12 | + | 1 | ÷ | 4 | × | x |
= | 12 | + | 1 4 | x |
12 | + | 1 4 | x | = | ( | 4 | ÷ | 3 | ) | x | + | 2 |
方程右边 = | 4 | ÷ | 3 | × | x | + | 2 |
= | 4 3 | x | + | 2 |
12 | + | 1 4 | x | = | 4 3 | x | + | 2 |
1 4 | x | − | 4 3 | x | = | 2 | − | 12 |
- | 13 12 | x | = | 2 | − | 12 |
- | 13 12 | x | = | - | 10 |
10 | = | 13 12 | x |
13 12 | x | = | 10 |
x | = | 10 | ÷ | 13 12 |
= | 10 | × | 12 13 |
x | = | 120 13 |
