X | ÷ | 87 | − | ( | 100 | − | X | ) | ÷ | 1650 | = | 167 1000 |
方程左边 = | 1 87 | X | − | 100 | × | 1 1650 | + | X | × | 1 1650 |
= | 1 87 | X | − | 2 33 | + | X | × | 1 1650 |
= | 193 15950 | X | − | 2 33 |
193 15950 | X | − | 2 33 | = | 167 1000 |
193 15950 | X | = | 167 1000 | + | 2 33 |
193 15950 | X | = | 7511 33000 |
X | = | 7511 33000 | ÷ | 193 15950 |
= | 7511 33000 | × | 15950 193 |
= | 7511 60 | × | 29 193 |
