| x | = | 50000 | − | ( | x | × | 7 25000 | × | 200 | ) |
| Right side of the equation = | 50000 | − | x | × | 7 25000 | × | 200 |
| = | 50000 | − | x | × | 7 125 |
| x | = | 50000 | − | 7 125 | x |
| x | + | 7 125 | x | = | 50000 |
132 125 | x | = | 50000 |
| x | = | 50000 | ÷ | 132 125 |
| = | 50000 | × | 125 132 |
| = | 12500 | × | 125 33 |
| x | = | 1562500 33 |
| x | = | 47348.484848 |
