1 2 | ( | x | − | 13 5 | ) | ÷ | 2 | = | 1 |
| Left side of the equation = | 1 4 | ( | x | − | 13 5 | ) |
1 4 | ( | x | − | 13 5 | ) | = | 1 |
| Left side of the equation = | 1 4 | x | − | 1 4 | × | 13 5 |
| = | 1 4 | x | − | 13 20 |
1 4 | x | − | 13 20 | = | 1 |
1 4 | x | = | 1 | + | 13 20 |
1 4 | x | = | 33 20 |
| x | = | 33 20 | ÷ | 1 4 |
| = | 33 20 | × | 4 |
| = | 33 5 | × | 1 |
| x | = | 33 5 |
| x | = | 6.6 |
