X | ÷ | 87 | − | 30 | ÷ | 1100 | − | 3 | ÷ | 45 | = | 167 100000 | ( | X | + | 33 | ) |
方程左边 = | X | × | 1 87 | − | 3 110 | − | 1 15 |
= | 1 87 | X | − | 31 330 |
1 87 | X | − | 31 330 | = | 167 100000 | ( | X | + | 33 | ) |
方程右边 = | 167 100000 | X | + | 167 100000 | × | 33 |
= | 167 100000 | X | + | 5511 100000 |
1 87 | X | − | 31 330 | = | 167 100000 | X | + | 5511 100000 |
1 87 | X | − | 167 100000 | X | = | 5511 100000 | + | 31 330 |
85471 8700000 | X | = | 5511 100000 | + | 31 330 |
85471 8700000 | X | = | 491863 3300000 |
X | = | 491863 3300000 | ÷ | 85471 8700000 |
= | 491863 3300000 | × | 8700000 85471 |
= | 491863 11 | × | 29 85471 |
