| = | 1 4 | x | + | ( | 3 | ÷ | 4 | ) | ( | ( | 1 | − | 4 | ) | x | ) | + | 24 |
| = | 1 4 | x | + | 3 | ÷ | 4 | × | ( | ( | 1 | − | 4 | ) | x | ) | + | 24 |
| = | 1 4 | x | + | 3 4 | ( | ( | 1 | − | 4 | ) | x | ) | + | 24 |
| = | 1 4 | x | + | 3 4 | ( | 1 | − | 4 | ) | x | + | 24 |
| = | 1 4 | x | + | 3 4 | × | 1 | x | − | 3 4 | × | 4 | x | + | 24 |
| = | 1 4 | x | + | 3 4 | x | − | 3 | x | + | 24 |
| = | - | 2 | x | + | 24 |
| - | 2 | x | + | 24 | = | x |
| - | 2 | x | − | x | = | - | 24 |
| - | 3 | x | = | - | 24 |
| 24 | = | 3 | x |
| 3 | x | = | 24 |
| x | = | 24 | ÷ | 3 |
| = | 24 | × | 1 3 |
| = | 8 | × | 1 |
