343 250 | x | + | ( | 100 | − | x | ) | ÷ | 100 | = | 32 25 |
| 方程左边 = | 343 250 | x | + | 100 | × | 1 100 | − | x | × | 1 100 |
| = | 343 250 | x | + | 1 | − | x | × | 1 100 |
| = | 681 500 | x | + | 1 |
681 500 | x | + | 1 | = | 32 25 |
681 500 | x | = | 32 25 | − | 1 |
681 500 | x | = | 7 25 |
| x | = | 7 25 | ÷ | 681 500 |
| = | 7 25 | × | 500 681 |
| = | 7 | × | 20 681 |
| x | = | 140 681 |
