6384 5 | + | ( | x | − | 800 | ) | × | 1 5 | = | x |
| Left side of the equation = | 6384 5 | + | x | × | 1 5 | − | 800 | × | 1 5 |
| = | 6384 5 | + | x | × | 1 5 | − | 160 |
| = | 5584 5 | + | 1 5 | x |
5584 5 | + | 1 5 | x | = | x |
1 5 | x | − | x | = | - | 5584 5 |
| - | 4 5 | x | = | - | 5584 5 |
5584 5 | = | 4 5 | x |
4 5 | x | = | 5584 5 |
| x | = | 5584 5 | ÷ | 4 5 |
| = | 5584 5 | × | 5 4 |
| = | 1396 | × | 1 |
| x | = | 1396 |
