| Left side of the equation = | 11 | ( | 2 | x | − | 3 | ) | + | 19 | ( | 3 | − | 2 | x | ) | + | 13 2 | x |
| 11 | ( | 2 | x | − | 3 | ) | + | 19 | ( | 3 | − | 2 | x | ) | + | 13 2 | x | = | 13 | ÷ | 3 |
| Left side of the equation = | 11 | × | 2 | x | − | 11 | × | 3 | + | 19 | ( | 3 | − | 2 | x | ) | + | 13 2 | x |
| = | 22 | x | − | 33 | + | 19 | ( | 3 | − | 2 | x | ) | + | 13 2 | x |
| = | 57 2 | x | − | 33 | + | 19 | ( | 3 | − | 2 | x | ) |
| = | 57 2 | x | − | 33 | + | 19 | × | 3 | − | 19 | × | 2 | x |
| = | 57 2 | x | − | 33 | + | 57 | − | 38 | x |
| = | - | 19 2 | x | + | 24 |
| - | 19 2 | x | + | 24 | = | 13 | ÷ | 3 |
| Right side of the equation = | 13 3 |
| - | 19 2 | x | + | 24 | = | 13 3 |
| - | 19 2 | x | = | 13 3 | − | 24 |
| - | 19 2 | x | = | - | 59 3 |
59 3 | = | 19 2 | x |
19 2 | x | = | 59 3 |
| x | = | 59 3 | ÷ | 19 2 |
| = | 59 3 | × | 2 19 |
