| 123 | x | ÷ | ( | 123 | + | 100 | x | ) | = | 283 400 |
| 方程两边同时乘以: | ( | 123 | + | 100 | x | ) |
| 123 | x | = | 283 400 | ( | 123 | + | 100 | x | ) |
| 123 | x | = | 283 400 | × | 123 | + | 283 400 | × | 100 | x |
| 123 | x | = | 34809 400 | + | 283 4 | x |
| 123 | x | − | 283 4 | x | = | 34809 400 |
209 4 | x | = | 34809 400 |
| x | = | 34809 400 | ÷ | 209 4 |
| = | 34809 400 | × | 4 209 |
| = | 34809 100 | × | 1 209 |
| x | = | 34809 20900 |
| x | = | 1.665502 |
