| ( | ( | 8 | + | x | ÷ | 10 | ) | × | 100 | ) | × | 1 100 | + | 5000 | = | 53000 |
| Left side of the equation = | ( | 8 | + | x | ÷ | 10 | ) | × | 100 | × | 1 100 | + | 5000 |
| = | ( | 8 | + | x | ÷ | 10 | ) | × | 1 | + | 5000 |
| = | 8 | × | 1 | + | x | ÷ | 10 | × | 1 | + | 5000 |
| = | 8 | + | x | × | 1 10 | + | 5000 |
| = | 5008 | + | 1 10 | x |
| 5008 | + | 1 10 | x | = | 53000 |
1 10 | x | = | 53000 | − | 5008 |
1 10 | x | = | 47992 |
| x | = | 47992 | ÷ | 1 10 |
| = | 47992 | × | 10 |
| x | = | 479920 |
