23 10 | ( | x | − | 51 100 | ) | = | 7 100 | × | 229 1000 |
| 方程左边 = | 23 10 | x | − | 23 10 | × | 51 100 |
| = | 23 10 | x | − | 1173 1000 |
23 10 | x | − | 1173 1000 | = | 7 100 | × | 229 1000 |
| 方程右边 = | 1603 100000 |
23 10 | x | − | 1173 1000 | = | 1603 100000 |
23 10 | x | = | 1603 100000 | + | 1173 1000 |
23 10 | x | = | 118903 100000 |
| x | = | 118903 100000 | ÷ | 23 10 |
| = | 118903 100000 | × | 10 23 |
| = | 118903 10000 | × | 1 23 |
| x | = | 118903 230000 |
| x | = | 0.51697 |
