| Left side of the equation = | 24 | − | x | − | ( | 26 | − | x | − | 2 | ) | × | 15 |
| 24 | − | x | − | ( | 26 | − | x | − | 2 | ) | × | 15 | = | 9 2 |
| Left side of the equation = | 24 | − | x | − | 26 | × | 15 | + | x | × | 15 | + | 2 | × | 15 |
| = | 24 | − | x | − | 390 | + | x | × | 15 | + | 30 |
| = | - | 336 | + | 14 | x |
| - | 336 | + | 14 | x | = | 9 2 |
| 14 | x | = | 9 2 | + | 336 |
| 14 | x | = | 681 2 |
| x | = | 681 2 | ÷ | 14 |
| = | 681 2 | × | 1 14 |
| x | = | 681 28 |
