| - | 1 | ÷ | 9 | × | ( | x | − | 6 | ) | + | 4 | = | 0 |
| Left side of the equation = | - | 1 9 | ( | x | − | 6 | ) | + | 4 |
| - | 1 9 | ( | x | − | 6 | ) | + | 4 | = | 0 |
| Left side of the equation = | - | 1 9 | x | + | 1 9 | × | 6 | + | 4 |
| = | - | 1 9 | x | + | 2 3 | + | 4 |
| = | - | 1 9 | x | + | 14 3 |
| - | 1 9 | x | + | 14 3 | = | 0 |
| - | 1 9 | x | = | 0 | − | 14 3 |
| - | 1 9 | x | = | - | 14 3 |
14 3 | = | 1 9 | x |
