( | 46 | − | X | ) | × | 23 15 | = | 58 | − | X |
方程左边 = | 46 | × | 23 15 | − | X | × | 23 15 |
= | 1058 15 | − | X | × | 23 15 |
1058 15 | − | 23 15 | X | = | 58 | − | X |
- | 23 15 | X | + | X | = | 58 | − | 1058 15 |
- | 8 15 | X | = | 58 | − | 1058 15 |
- | 8 15 | X | = | - | 188 15 |
188 15 | = | 8 15 | X |
8 15 | X | = | 188 15 |
X | = | 188 15 | ÷ | 8 15 |
= | 188 15 | × | 15 8 |
= | 47 | × | 1 2 |
