1 | ÷ | 4 | × | ( | x | − | 1 | ) | = | 1 | ÷ | 3 | × | ( | x | − | 18 5 | − | 1 | ) |
方程左边 = | 1 4 | ( | x | − | 1 | ) |
1 4 | ( | x | − | 1 | ) | = | 1 | ÷ | 3 | × | ( | x | − | 18 5 | − | 1 | ) |
方程左边 = | 1 4 | x | − | 1 4 | × | 1 |
= | 1 4 | x | − | 1 4 |
1 4 | x | − | 1 4 | = | 1 | ÷ | 3 | × | ( | x | − | 18 5 | − | 1 | ) |
方程右边 = | 1 3 | ( | x | − | 18 5 | − | 1 | ) |
1 4 | x | − | 1 4 | = | 1 3 | ( | x | − | 18 5 | − | 1 | ) |
方程右边 = | 1 3 | x | − | 1 3 | × | 18 5 | − | 1 3 | × | 1 |
= | 1 3 | x | − | 6 5 | − | 1 3 |
= | 1 3 | x | − | 23 15 |
1 4 | x | − | 1 4 | = | 1 3 | x | − | 23 15 |
1 4 | x | − | 1 3 | x | = | - | 23 15 | + | 1 4 |
- | 1 12 | x | = | - | 23 15 | + | 1 4 |
- | 1 12 | x | = | - | 77 60 |
77 60 | = | 1 12 | x |
1 12 | x | = | 77 60 |
x | = | 77 60 | ÷ | 1 12 |
= | 77 60 | × | 12 |
= | 77 5 | × | 1 |
x | = | 77 5 |
x | = | 15.4 |
