| x | − | ( | 2 | ÷ | 11 | ) | x | = | 180 | − | x | + | ( | 2 | ÷ | 11 | ) | x |
| Left side of the equation = | x | − | 2 | ÷ | 11 | × | x |
| = | x | − | 2 11 | x |
| = | 9 11 | x |
9 11 | x | = | 180 | − | x | + | ( | 2 | ÷ | 11 | ) | x |
| Right side of the equation = | 180 | − | x | + | 2 | ÷ | 11 | × | x |
| = | 180 | − | x | + | 2 11 | x |
| = | 180 | − | 9 11 | x |
9 11 | x | = | 180 | − | 9 11 | x |
9 11 | x | + | 9 11 | x | = | 180 |
18 11 | x | = | 180 |
| x | = | 180 | ÷ | 18 11 |
| = | 180 | × | 11 18 |
| = | 10 | × | 11 |
| x | = | 110 |
