| 2300 | x | + | 2400 | ( | 176 | − | x | ) | = | 333180 |
| 方程左边 = | 2300 | x | + | 2400 | × | 176 | − | 2400 | x |
| = | 2300 | x | + | 422400 | − | 2400 | x |
| = | - | 100 | x | + | 422400 |
| - | 100 | x | + | 422400 | = | 333180 |
| - | 100 | x | = | 333180 | − | 422400 |
| - | 100 | x | = | - | 89220 |
| 89220 | = | 100 | x |
| 100 | x | = | 89220 |
| x | = | 89220 | ÷ | 100 |
| = | 89220 | × | 1 100 |
| = | 4461 | × | 1 5 |
| x | = | 4461 5 |
| x | = | 892.2 |
