( | X | − | X | ÷ | 113 100 | × | 13 100 | ) | ÷ | 729 100 | = | 91 1250 |
方程左边 = | X | × | 100 729 | − | X | ÷ | 113 100 | × | 13 100 | × | 100 729 |
= | X | × | 100 729 | − | X | × | 1300 82377 |
= | 10000 82377 | X |
10000 82377 | X | = | 91 1250 |
X | = | 91 1250 | ÷ | 10000 82377 |
= | 91 1250 | × | 82377 10000 |
