| 方程左边 = | 16 5 | x | − | 16 5 | × | 3 | − | 5 | ( | 2 | x | + | 1 | ) |
| = | 16 5 | x | − | 48 5 | − | 5 | ( | 2 | x | + | 1 | ) |
| = | 16 5 | x | − | 48 5 | − | 5 | × | 2 | x | − | 5 | × | 1 |
| = | 16 5 | x | − | 48 5 | − | 10 | x | − | 5 |
| = | - | 34 5 | x | − | 73 5 |
| - | 34 5 | x | − | 73 5 | = | 4 | − | 3 | ( | x | + | 2 | ) |
| 方程右边 = | 4 | − | 3 | x | − | 3 | × | 2 |
| = | 4 | − | 3 | x | − | 6 |
| = | - | 2 | − | 3 | x |
| - | 34 5 | x | − | 73 5 | = | - | 2 | − | 3 | x |
| - | 34 5 | x | + | 3 | x | = | - | 2 | + | 73 5 |
| - | 19 5 | x | = | - | 2 | + | 73 5 |
| - | 19 5 | x | = | 63 5 |
| - | 63 5 | = | 19 5 | x |
19 5 | x | = | - | 63 5 |
| x | = | - | 63 5 | ÷ | 19 5 |
| = | - | 63 5 | × | 5 19 |
| = | - | 63 | × | 1 19 |
| x | = | - | 63 19 |
| x | = | - 3.315789 |
