| 998 | ( | 100 | + | x | ) | = | 100000 | ( | 1 | + | 76 500 | ) |
| Left side of the equation = | 998 | × | 100 | + | 998 | x |
| = | 99800 | + | 998 | x |
| 99800 | + | 998 | x | = | 100000 | ( | 1 | + | 76 500 | ) |
| Right side of the equation = | 100000 | × | 1 | + | 100000 | × | 76 500 |
| = | 100000 | + | 15200 |
| = | 115200 |
| 99800 | + | 998 | x | = | 115200 |
| 998 | x | = | 115200 | − | 99800 |
| 998 | x | = | 15400 |
| x | = | 15400 | ÷ | 998 |
| = | 15400 | × | 1 998 |
| = | 7700 | × | 1 499 |
| x | = | 7700 499 |
| x | = | 15.430862 |
