方程左边 = | 359 250 | X | + | 7937 1000 | × | 75 | − | 7937 1000 | X |
= | 359 250 | X | + | 23811 40 | − | 7937 1000 | X |
= | - | 6501 1000 | X | + | 23811 40 |
- | 6501 1000 | X | + | 23811 40 | = | 143 |
- | 6501 1000 | X | = | 143 | − | 23811 40 |
- | 6501 1000 | X | = | - | 18091 40 |
18091 40 | = | 6501 1000 | X |
6501 1000 | X | = | 18091 40 |
X | = | 18091 40 | ÷ | 6501 1000 |
= | 18091 40 | × | 1000 6501 |
= | 18091 | × | 25 6501 |
