| ( | ( | 5 | x | − | 1 | ) | ÷ | 6 | ) | − | 1 | = | ( | 7 | ÷ | 3 | ) |
| Left side of the equation = | ( | 5 | x | − | 1 | ) | ÷ | 6 | − | 1 |
| = | 5 | x | × | 1 6 | − | 1 | × | 1 6 | − | 1 |
| = | 5 6 | x | − | 1 6 | − | 1 |
| = | 5 6 | x | − | 7 6 |
5 6 | x | − | 7 6 | = | ( | 7 | ÷ | 3 | ) |
| Right side of the equation = | 7 | ÷ | 3 |
| = | 7 3 |
5 6 | x | − | 7 6 | = | 7 3 |
5 6 | x | = | 7 3 | + | 7 6 |
5 6 | x | = | 7 2 |
| x | = | 7 2 | ÷ | 5 6 |
| = | 7 2 | × | 6 5 |
| = | 7 | × | 3 5 |
| x | = | 21 5 |
| x | = | 4.2 |
