| ( | 5 | ÷ | 16 | ) | ( | x | + | 4 | ) | = | ( | 1 | ÷ | 4 | ) | x | + | 4 |
| 方程左边 = | 5 | ÷ | 16 | × | ( | x | + | 4 | ) |
| = | 5 16 | ( | x | + | 4 | ) |
| = | 5 16 | x | + | 5 16 | × | 4 |
| = | 5 16 | x | + | 5 4 |
5 16 | x | + | 5 4 | = | ( | 1 | ÷ | 4 | ) | x | + | 4 |
| 方程右边 = | 1 | ÷ | 4 | × | x | + | 4 |
| = | 1 4 | x | + | 4 |
5 16 | x | + | 5 4 | = | 1 4 | x | + | 4 |
5 16 | x | − | 1 4 | x | = | 4 | − | 5 4 |
1 16 | x | = | 4 | − | 5 4 |
1 16 | x | = | 11 4 |
| x | = | 11 4 | ÷ | 1 16 |
| = | 11 4 | × | 16 |
| = | 11 | × | 4 |
| x | = | 44 |
