| ( | 47 | + | x | ) | ÷ | ( | 47 | + | 3 | + | x | ) | = | 95 100 |
| 方程两边同时乘以: | ( | 47 | + | 3 | + | x | ) |
| ( | 47 | + | x | ) | = | 95 100 | ( | 47 | + | 3 | + | x | ) |
| 47 | + | x | = | 95 100 | ( | 47 | + | 3 | + | x | ) |
| 47 | + | x | = | 95 100 | × | 47 | + | 95 100 | × | 3 | + | 95 100 | x |
| 47 | + | x | = | 893 20 | + | 57 20 | + | 95 100 | x |
| 47 | + | x | = | 95 2 | + | 95 100 | x |
| x | − | 95 100 | x | = | 95 2 | − | 47 |
1 20 | x | = | 95 2 | − | 47 |
1 20 | x | = | 1 2 |
| x | = | 1 2 | ÷ | 1 20 |
| = | 1 2 | × | 20 |
| = | 1 | × | 10 |
| x | = | 10 |
