| ( | 2000 | + | 500 | ) | ÷ | ( | 64833 50 | + | X | ) | = | 77 50 |
| Multiply both sides of the equation by: | ( | 64833 50 | + | X | ) |
| ( | 2000 | + | 500 | ) | = | 77 50 | ( | 64833 50 | + | X | ) |
| 2000 | + | 500 | = | 77 50 | ( | 64833 50 | + | X | ) |
| 2000 | + | 500 | = | 77 50 | × | 64833 50 | + | 77 50 | X |
| 2000 | + | 500 | = | 4992141 2500 | + | 77 50 | X |
| 2500 | = | 4992141 2500 | + | 77 50 | X |
| - | 77 50 | X | = | 4992141 2500 | − | 2500 |
| - | 77 50 | X | = | - | 1257859 2500 |
1257859 2500 | = | 77 50 | X |
77 50 | X | = | 1257859 2500 |
| X | = | 1257859 2500 | ÷ | 77 50 |
| = | 1257859 2500 | × | 50 77 |
| = | 1257859 50 | × | 1 77 |
| X | = | 1257859 3850 |
| X | = | 326.716623 |
