| 3 | ÷ | 4 | × | ( | x | − | 1 | ÷ | 4 | ) | = | 12 |
| Left side of the equation = | 3 4 | ( | x | − | 1 | ÷ | 4 | ) |
3 4 | ( | x | − | 1 | ÷ | 4 | ) | = | 12 |
| Left side of the equation = | 3 4 | x | − | 3 4 | × | 1 | ÷ | 4 |
| = | 3 4 | x | − | 3 16 |
3 4 | x | − | 3 16 | = | 12 |
3 4 | x | = | 12 | + | 3 16 |
3 4 | x | = | 195 16 |
| x | = | 195 16 | ÷ | 3 4 |
| = | 195 16 | × | 4 3 |
| = | 65 4 | × | 1 |
| x | = | 65 4 |
| x | = | 16.25 |
