| 2 | ÷ | 7 | × | ( | 3 | x | + | 7 | ) | = | 2 | − | ( | 3 | ÷ | 2 | ) | x |
| Left side of the equation = | 2 7 | ( | 3 | x | + | 7 | ) |
2 7 | ( | 3 | x | + | 7 | ) | = | 2 | − | ( | 3 | ÷ | 2 | ) | x |
| Left side of the equation = | 2 7 | × | 3 | x | + | 2 7 | × | 7 |
| = | 6 7 | x | + | 2 |
6 7 | x | + | 2 | = | 2 | − | ( | 3 | ÷ | 2 | ) | x |
| Right side of the equation = | 2 | − | 3 | ÷ | 2 | × | x |
| = | 2 | − | 3 2 | x |
6 7 | x | + | 2 | = | 2 | − | 3 2 | x |
6 7 | x | + | 3 2 | x | = | 2 | − | 2 |
33 14 | x | = | 2 | − | 2 |
33 14 | x | = | 0 |
| x | = | 0 | ÷ | 33 14 |
| = | 0 | × | 14 33 |
