| 1 | x | ÷ | 3 | − | 1 | ÷ | 3 | = | 1 | x | ÷ | 4 | + | 1 | ÷ | 4 |
| Left side of the equation = | 1 3 | x | − | 1 3 |
1 3 | x | − | 1 3 | = | 1 | x | ÷ | 4 | + | 1 | ÷ | 4 |
| Right side of the equation = | 1 4 | x | + | 1 4 |
1 3 | x | − | 1 3 | = | 1 4 | x | + | 1 4 |
1 3 | x | − | 1 4 | x | = | 1 4 | + | 1 3 |
1 12 | x | = | 1 4 | + | 1 3 |
1 12 | x | = | 7 12 |
| x | = | 7 12 | ÷ | 1 12 |
| = | 7 12 | × | 12 |
| = | 7 | × | 1 |
| x | = | 7 |
