1 10 | x | ÷ | ( | 1500 | + | x | ) | = | 1 2 | ÷ | 100 |
| 方程两边同时乘以: | ( | 1500 | + | x | ) |
1 10 | x | = | 1 2 | ÷ | 100 | × | ( | 1500 | + | x | ) |
1 10 | x | = | 1 2 | ÷ | 100 | × | 1500 | + | 1 2 | ÷ | 100 | × | x |
1 10 | x | = | 15 2 | + | 1 200 | x |
1 10 | x | − | 1 200 | x | = | 15 2 |
19 200 | x | = | 15 2 |
| x | = | 15 2 | ÷ | 19 200 |
| = | 15 2 | × | 200 19 |
| = | 15 | × | 100 19 |
| x | = | 1500 19 |
| x | = | 78.947368 |
