| x | × | 10 | + | 48 | × | 5 | × | 5 2 | = | 60 | × | 5 | + | 48 | × | 10 | × | 5 | + | 600 | × | 5 |
| Left side of the equation = | x | × | 10 | + | 600 |
| 10 | x | + | 600 | = | 60 | × | 5 | + | 48 | × | 10 | × | 5 | + | 600 | × | 5 |
| Right side of the equation = | 300 | + | 2400 | + | 3000 |
| = | 5700 |
| 10 | x | + | 600 | = | 5700 |
| 10 | x | = | 5700 | − | 600 |
| 10 | x | = | 5100 |
| x | = | 5100 | ÷ | 10 |
| = | 5100 | × | 1 10 |
| = | 510 | × | 1 |
| x | = | 510 |
