36 25 | = | 21 5 | × | 139 50 | X | ÷ | ( | X | + | 1400 | ) |
| Multiply both sides of the equation by: | ( | X | + | 1400 | ) |
36 25 | ( | X | + | 1400 | ) | = | 21 5 | × | 139 50 | X |
36 25 | X | + | 36 25 | × | 1400 | = | 21 5 | × | 139 50 | X |
36 25 | X | + | 2016 | = | 2919 250 | X |
36 25 | X | − | 2919 250 | X | = | - | 2016 |
| - | 2559 250 | X | = | - | 2016 |
| 2016 | = | 2559 250 | X |
2559 250 | X | = | 2016 |
| X | = | 2016 | ÷ | 2559 250 |
| = | 2016 | × | 250 2559 |
| = | 672 | × | 250 853 |
| X | = | 168000 853 |
| X | = | 196.951934 |
