X | ÷ | 87 | − | 20 | ÷ | 1100 | − | 10 | ÷ | 200 | = | 167 100000 | ( | X | + | 30 | ) |
方程左边 = | X | × | 1 87 | − | 1 55 | − | 1 20 |
= | 1 87 | X | − | 3 44 |
1 87 | X | − | 3 44 | = | 167 100000 | ( | X | + | 30 | ) |
方程右边 = | 167 100000 | X | + | 167 100000 | × | 30 |
= | 167 100000 | X | + | 501 10000 |
1 87 | X | − | 3 44 | = | 167 100000 | X | + | 501 10000 |
1 87 | X | − | 167 100000 | X | = | 501 10000 | + | 3 44 |
85471 8700000 | X | = | 501 10000 | + | 3 44 |
85471 8700000 | X | = | 13011 110000 |
X | = | 13011 110000 | ÷ | 85471 8700000 |
= | 13011 110000 | × | 8700000 85471 |
= | 13011 11 | × | 870 85471 |
