10 | x | − | 5 | ( | 1 | − | x | ) | = | 5 | ( | 1 10 | x | + | 1 5 | ) | − | 10 |
方程左边 = | 10 | x | − | 5 | × | 1 | + | 5 | x |
= | 10 | x | − | 5 | + | 5 | x |
= | 15 | x | − | 5 |
15 | x | − | 5 | = | 5 | ( | 1 10 | x | + | 1 5 | ) | − | 10 |
方程右边 = | 5 | × | 1 10 | x | + | 5 | × | 1 5 | − | 10 |
= | 1 2 | x | + | 1 | − | 10 |
= | 1 2 | x | − | 9 |
15 | x | − | 5 | = | 1 2 | x | − | 9 |
15 | x | − | 1 2 | x | = | - | 9 | + | 5 |
29 2 | x | = | - | 9 | + | 5 |
29 2 | x | = | - | 4 |
x | = | - | 4 | ÷ | 29 2 |
= | - | 4 | × | 2 29 |
x | = | - | 8 29 |
x | = | - 0.275862 |
