12 5 | − | x | − | 4 | ÷ | 5 2 | = | 3 | ÷ | 5 | × | x |
| Left side of the equation = | 12 5 | − | x | − | 8 5 |
| = | 4 5 | − | x |
4 5 | − | x | = | 3 | ÷ | 5 | × | x |
| Right side of the equation = | 3 5 | x |
4 5 | − | x | = | 3 5 | x |
| - | x | − | 3 5 | x | = | - | 4 5 |
| - | 8 5 | x | = | - | 4 5 |
4 5 | = | 8 5 | x |
8 5 | x | = | 4 5 |
| x | = | 4 5 | ÷ | 8 5 |
| = | 4 5 | × | 5 8 |
| = | 1 | × | 1 2 |
| x | = | 1 2 |
| x | = | 0.5 |
