| 3 | x | + | 2 | ÷ | 2 | − | 1 | = | 2 | x | − | 1 | ÷ | 4 | − | 2 | x | + | 1 | ÷ | 5 |
| Left side of the equation = | 3 | x | + | 1 | − | 1 |
| = | 3 | x | + | 0 |
| 3 | x | + | 0 | = | 2 | x | − | 1 | ÷ | 4 | − | 2 | x | + | 1 | ÷ | 5 |
| Right side of the equation = | 2 | x | − | 1 4 | − | 2 | x | + | 1 5 |
| = | 0 | x | − | 1 20 |
| 3 | x | + | 0 | = | 0 | x | − | 1 20 |
| x | = | - | 1 20 | ÷ | 3 |
| = | - | 1 20 | × | 1 3 |
| x | = | - | 1 60 |
| x | = | - 0.016667 |
