5 4 | ( | 1 | + | 5100 | ÷ | X | ) | = | 10 |
5 4 | × | 1 | + | 5 4 | × | 5100 | ÷ | X | = | 10 |
5 4 | + | 6375 | ÷ | X | = | 10 |
| Multiply both sides of the equation by: | X |
5 4 | X | + | 6375 | = | 10 | X |
5 4 | X | − | 10 | X | = | - | 6375 |
| - | 35 4 | X | = | - | 6375 |
| 6375 | = | 35 4 | X |
35 4 | X | = | 6375 |
| X | = | 6375 | ÷ | 35 4 |
| = | 6375 | × | 4 35 |
| = | 1275 | × | 4 7 |
| X | = | 5100 7 |
| X | = | 728.571429 |
