X | ÷ | 87 | − | 20 | ÷ | 1900 | − | 10 | ÷ | 167 | = | 167 100000 | ( | X | + | 30 | ) |
方程左边 = | X | × | 1 87 | − | 1 95 | − | 10 167 |
= | 1 87 | X | − | 1117 15865 |
1 87 | X | − | 1117 15865 | = | 167 100000 | ( | X | + | 30 | ) |
方程右边 = | 167 100000 | X | + | 167 100000 | × | 30 |
= | 167 100000 | X | + | 501 10000 |
1 87 | X | − | 1117 15865 | = | 167 100000 | X | + | 501 10000 |
1 87 | X | − | 167 100000 | X | = | 501 10000 | + | 1117 15865 |
