( | ( | 1 | × | 9 10 | ) | + | X | ) | × | 103 100 | = | 1 | + | X |
方程左边 = | ( | 1 | × | 9 10 | ) | × | 103 100 | + | X | × | 103 100 |
= | 1 | × | 9 10 | × | 103 100 | + | 103 100 | X |
= | 927 1000 | + | 103 100 | X |
927 1000 | + | 103 100 | X | = | 1 | + | X |
103 100 | X | − | X | = | 1 | − | 927 1000 |
3 100 | X | = | 1 | − | 927 1000 |
3 100 | X | = | 73 1000 |
X | = | 73 1000 | ÷ | 3 100 |
= | 73 1000 | × | 100 3 |
= | 73 10 | × | 1 3 |
X | = | 73 30 |
X | = | 2.433333 |
