X | ÷ | 87 | − | ( | 947 10 | − | X | ) | ÷ | 1000 | = | 113 250 |
方程左边 = | 1 87 | X | − | 947 10 | × | 1 1000 | + | X | × | 1 1000 |
= | 1 87 | X | − | 947 10000 | + | X | × | 1 1000 |
= | 1087 87000 | X | − | 947 10000 |
1087 87000 | X | − | 947 10000 | = | 113 250 |
1087 87000 | X | = | 113 250 | + | 947 10000 |
1087 87000 | X | = | 5467 10000 |
X | = | 5467 10000 | ÷ | 1087 87000 |
= | 5467 10000 | × | 87000 1087 |
= | 5467 10 | × | 87 1087 |
X | = | 475629 10870 |
X | = | 43.756118 |
