| X | = | 10000 | + | ( | 15000 | + | 2 | X | ÷ | 7 | ) | ÷ | 7 |
| Right side of the equation = | 10000 | + | 15000 | × | 1 7 | + | 2 | X | ÷ | 7 | × | 1 7 |
| = | 10000 | + | 15000 7 | + | 2 49 | X |
| = | 85000 7 | + | 2 49 | X |
| X | = | 85000 7 | + | 2 49 | X |
| X | − | 2 49 | X | = | 85000 7 |
47 49 | X | = | 85000 7 |
| X | = | 85000 7 | ÷ | 47 49 |
| = | 85000 7 | × | 49 47 |
| = | 85000 | × | 7 47 |
| X | = | 595000 47 |
| X | = | 12659.574468 |
