X | ÷ | 87 | − | ( | 95 | − | X | ) | ÷ | 100 | = | 73 100 |
方程左边 = | 1 87 | X | − | 95 | × | 1 100 | + | X | × | 1 100 |
= | 1 87 | X | − | 19 20 | + | X | × | 1 100 |
= | 187 8700 | X | − | 19 20 |
187 8700 | X | − | 19 20 | = | 73 100 |
187 8700 | X | = | 73 100 | + | 19 20 |
187 8700 | X | = | 42 25 |
X | = | 42 25 | ÷ | 187 8700 |
= | 42 25 | × | 8700 187 |
= | 42 | × | 348 187 |
X | = | 14616 187 |
X | = | 78.160428 |
