| 9 | x | + | 23 | + | 10 | = | 14 | x | ( | 1 | + | 3 | ÷ | 7 | ) |
| Left side of the equation = | 9 | x | + | 33 |
| 9 | x | + | 33 | = | 14 | x | ( | 1 | + | 3 | ÷ | 7 | ) |
| Right side of the equation = | 14 | x | × | 1 | + | 14 | x | × | 3 | ÷ | 7 |
| = | 14 | x | + | 6 | x |
| = | 20 | x |
| 9 | x | + | 33 | = | 20 | x |
| 9 | x | − | 20 | x | = | - | 33 |
| - | 11 | x | = | - | 33 |
| 33 | = | 11 | x |
| 11 | x | = | 33 |
| x | = | 33 | ÷ | 11 |
| = | 33 | × | 1 11 |
| = | 3 | × | 1 |
| x | = | 3 |
