X | ÷ | 87 | − | ( | 95 | − | X | ) | ÷ | 125 | = | 73 100 |
方程左边 = | 1 87 | X | − | 95 | × | 1 125 | + | X | × | 1 125 |
= | 1 87 | X | − | 19 25 | + | X | × | 1 125 |
= | 212 10875 | X | − | 19 25 |
212 10875 | X | − | 19 25 | = | 73 100 |
212 10875 | X | = | 73 100 | + | 19 25 |
212 10875 | X | = | 149 100 |
X | = | 149 100 | ÷ | 212 10875 |
= | 149 100 | × | 10875 212 |
= | 149 4 | × | 435 212 |
X | = | 64815 848 |
X | = | 76.432783 |
