方程左边 = | 43 50 | X | + | 37 5 | × | 950 | − | 37 5 | X |
= | 43 50 | X | + | 7030 | − | 37 5 | X |
= | - | 327 50 | X | + | 7030 |
- | 327 50 | X | + | 7030 | = | 119 50 |
- | 327 50 | X | = | 119 50 | − | 7030 |
- | 327 50 | X | = | - | 351381 50 |
351381 50 | = | 327 50 | X |
327 50 | X | = | 351381 50 |
X | = | 351381 50 | ÷ | 327 50 |
= | 351381 50 | × | 50 327 |
= | 117127 | × | 1 109 |
X | = | 117127 109 |
