X | ÷ | 193 | − | ( | 100 | − | X | ) | ÷ | 1000 | = | 143 1000 |
方程左边 = | 1 193 | X | − | 100 | × | 1 1000 | + | X | × | 1 1000 |
= | 1 193 | X | − | 1 10 | + | X | × | 1 1000 |
= | 1193 193000 | X | − | 1 10 |
1193 193000 | X | − | 1 10 | = | 143 1000 |
1193 193000 | X | = | 143 1000 | + | 1 10 |
1193 193000 | X | = | 243 1000 |
X | = | 243 1000 | ÷ | 1193 193000 |
= | 243 1000 | × | 193000 1193 |
= | 243 | × | 193 1193 |
X | = | 46899 1193 |
