| 4 | x | + | 3 | ( | 2 | x | − | 3 | ) | = | 12 | − | ( | x | + | 4 | ) |
| Left side of the equation = | 4 | x | + | 3 | × | 2 | x | − | 3 | × | 3 |
| = | 4 | x | + | 6 | x | − | 9 |
| = | 10 | x | − | 9 |
| 10 | x | − | 9 | = | 12 | − | ( | x | + | 4 | ) |
| Right side of the equation = | 12 | − | x | − | 4 |
| = | 8 | − | x |
| 10 | x | − | 9 | = | 8 | − | x |
| 10 | x | + | x | = | 8 | + | 9 |
| 11 | x | = | 8 | + | 9 |
| 11 | x | = | 17 |
| x | = | 17 | ÷ | 11 |
| = | 17 | × | 1 11 |
| x | = | 17 11 |
| x | = | 1.545455 |
