| 460 | × | 5 | + | 230 | ( | x | + | 5 | ) | = | 9200 |
| Left side of the equation = | 2300 | + | 230 | ( | x | + | 5 | ) |
| 2300 | + | 230 | ( | x | + | 5 | ) | = | 9200 |
| Left side of the equation = | 2300 | + | 230 | x | + | 230 | × | 5 |
| = | 2300 | + | 230 | x | + | 1150 |
| = | 3450 | + | 230 | x |
| 3450 | + | 230 | x | = | 9200 |
| 230 | x | = | 9200 | − | 3450 |
| 230 | x | = | 5750 |
| x | = | 5750 | ÷ | 230 |
| = | 5750 | × | 1 230 |
| = | 25 | × | 1 |
| x | = | 25 |
