( | x | − | x | ÷ | 113 100 | × | 13 100 | ) | ÷ | 727 100 | = | 79 1000 |
方程左边 = | x | × | 100 727 | − | x | ÷ | 113 100 | × | 13 100 | × | 100 727 |
= | x | × | 100 727 | − | x | × | 1300 82151 |
= | 10000 82151 | x |
10000 82151 | x | = | 79 1000 |
x | = | 79 1000 | ÷ | 10000 82151 |
= | 79 1000 | × | 82151 10000 |
x | = | 6489929 10000000 |
