| 37440 | ( | x | + | 3 200 | ) | = | 37740 | x |
| Left side of the equation = | 37440 | x | + | 37440 | × | 3 200 |
| = | 37440 | x | + | 2808 5 |
| 37440 | x | + | 2808 5 | = | 37740 | x |
| 37440 | x | − | 37740 | x | = | - | 2808 5 |
| - | 300 | x | = | - | 2808 5 |
2808 5 | = | 300 | x |
| 300 | x | = | 2808 5 |
| x | = | 2808 5 | ÷ | 300 |
| = | 2808 5 | × | 1 300 |
| = | 234 5 | × | 1 25 |
| x | = | 234 125 |
| x | = | 1.872 |
