| ( | x | − | 3 | ) | + | ( | x | + | 3 | ) | + | ( | x | ÷ | 3 | ) | + | 3 | x | = | 48 |
| Left side of the equation = | x | − | 3 | + | ( | x | + | 3 | ) | + | ( | x | ÷ | 3 | ) | + | 3 | x |
| = | 4 | x | − | 3 | + | ( | x | + | 3 | ) | + | ( | x | ÷ | 3 | ) |
| = | 4 | x | − | 3 | + | x | + | 3 | + | ( | x | ÷ | 3 | ) |
| = | 5 | x | − | 0 | + | ( | x | ÷ | 3 | ) |
| = | 5 | x | − | 0 | + | x | ÷ | 3 |
| = | 16 3 | x | − | 0 |
16 3 | x | − | 0 | = | 48 |
| x | = | 48 | ÷ | 16 3 |
| = | 48 | × | 3 16 |
| = | 3 | × | 3 |
| x | = | 9 |
