| 6 | ( | ( | 4 | ÷ | 3 | ) | x | + | 50 | ) | − | 6 | x | = | 800 |
| Left side of the equation = | 6 | ( | 4 | ÷ | 3 | ) | x | + | 6 | × | 50 | − | 6 | x |
| = | 6 | ( | 4 | ÷ | 3 | ) | x | + | 300 | − | 6 | x |
| = | 6 | × | 4 | ÷ | 3 | × | x | + | 300 | − | 6 | x |
| = | 8 | x | + | 300 | − | 6 | x |
| = | 2 | x | + | 300 |
| 2 | x | + | 300 | = | 800 |
| 2 | x | = | 800 | − | 300 |
| 2 | x | = | 500 |
| x | = | 500 | ÷ | 2 |
| = | 500 | × | 1 2 |
| = | 250 | × | 1 |
| x | = | 250 |
