| 6 | ( | 4 | x | + | 3 | ) | − | 6 | ( | x | + | 49 | ) | = | 0 |
| Left side of the equation = | 6 | × | 4 | x | + | 6 | × | 3 | − | 6 | ( | x | + | 49 | ) |
| = | 24 | x | + | 18 | − | 6 | ( | x | + | 49 | ) |
| = | 24 | x | + | 18 | − | 6 | x | − | 6 | × | 49 |
| = | 24 | x | + | 18 | − | 6 | x | − | 294 |
| = | 18 | x | − | 276 |
| 18 | x | − | 276 | = | 0 |
| 18 | x | = | 0 | + | 276 |
| 18 | x | = | 276 |
| x | = | 276 | ÷ | 18 |
| = | 276 | × | 1 18 |
| = | 46 | × | 1 3 |
| x | = | 46 3 |
| x | = | 15.333333 |
