| ( | 500 | + | x | ) | × | 32 | = | 1623 50 | × | 500 | + | 63 2 | x |
| 方程左边 = | 500 | × | 32 | + | x | × | 32 |
| = | 16000 | + | x | × | 32 |
| 16000 | + | 32 | x | = | 1623 50 | × | 500 | + | 63 2 | x |
| 方程右边 = | 16230 | + | 63 2 | x |
| 16000 | + | 32 | x | = | 16230 | + | 63 2 | x |
| 32 | x | − | 63 2 | x | = | 16230 | − | 16000 |
1 2 | x | = | 16230 | − | 16000 |
1 2 | x | = | 230 |
| x | = | 230 | ÷ | 1 2 |
| = | 230 | × | 2 |
| x | = | 460 |
