方程左边 = | x | + | 10 |
x | + | 10 | = | 3 | x | + | 2 | × | 3 | + | 1 | × | 1 | + | 0 | × | 6 | + | 1 |
方程右边 = | 3 | x | + | 6 | + | 1 | + | 0 | + | 1 |
= | 3 | x | + | 8 |
x | + | 10 | = | 3 | x | + | 8 |
x | − | 3 | x | = | 8 | − | 10 |
- | 2 | x | = | 8 | − | 10 |
- | 2 | x | = | - | 2 |
2 | = | 2 | x |
2 | x | = | 2 |
x | = | 2 | ÷ | 2 |
= | 2 | × | 1 2 |
= | 1 | × | 1 |
x | = | 1 |
