3 2 | x | + | 3 2 | × | 1 | = | 5 4 | × | 3 | x | − | 5 4 | × | 2 |
| 方程左边 = | 3 2 | x | + | 3 2 |
3 2 | x | + | 3 2 | = | 5 4 | × | 3 | x | − | 5 4 | × | 2 |
| 方程右边 = | 15 4 | x | − | 5 2 |
3 2 | x | + | 3 2 | = | 15 4 | x | − | 5 2 |
3 2 | x | − | 15 4 | x | = | - | 5 2 | − | 3 2 |
| - | 9 4 | x | = | - | 5 2 | − | 3 2 |
| - | 9 4 | x | = | - | 4 |
| 4 | = | 9 4 | x |
9 4 | x | = | 4 |
| x | = | 4 | ÷ | 9 4 |
| = | 4 | × | 4 9 |
| x | = | 16 9 |
| x | = | 1.777778 |
