| X | = | ( | 5250 | X | × | 6 100 | + | 339000 | + | 40075 | ) | ÷ | ( | 5250 | × | 12 100 | ) |
| Multiply both sides of the equation by: | ( | 5250 | × | 12 100 | ) |
| X | ( | 5250 | × | 12 100 | ) | = | ( | 5250 | X | × | 6 100 | + | 339000 | + | 40075 | ) |
| X | × | 5250 | × | 12 100 | = | ( | 5250 | X | × | 6 100 | + | 339000 | + | 40075 | ) |
| X | × | 5250 | × | 12 100 | = | 5250 | X | × | 6 100 | + | 339000 | + | 40075 |
| X | × | 630 | = | 315 | X | + | 339000 | + | 40075 |
| 630 | X | = | 315 | X | + | 379075 |
| 630 | X | − | 315 | X | = | 379075 |
| 315 | X | = | 379075 |
| X | = | 379075 | ÷ | 315 |
| = | 379075 | × | 1 315 |
| = | 75815 | × | 1 63 |
| X | = | 75815 63 |
| X | = | 1203.412698 |
