X | ÷ | 87 | − | 25 | ÷ | 1100 | − | 3 | ÷ | 45 | = | 167 100000 | ( | X | + | 28 | ) |
方程左边 = | X | × | 1 87 | − | 1 44 | − | 1 15 |
= | 1 87 | X | − | 59 660 |
1 87 | X | − | 59 660 | = | 167 100000 | ( | X | + | 28 | ) |
方程右边 = | 167 100000 | X | + | 167 100000 | × | 28 |
= | 167 100000 | X | + | 1169 25000 |
1 87 | X | − | 59 660 | = | 167 100000 | X | + | 1169 25000 |
1 87 | X | − | 167 100000 | X | = | 1169 25000 | + | 59 660 |
85471 8700000 | X | = | 1169 25000 | + | 59 660 |
85471 8700000 | X | = | 112327 825000 |
X | = | 112327 825000 | ÷ | 85471 8700000 |
= | 112327 825000 | × | 8700000 85471 |
= | 112327 11 | × | 116 85471 |
