| ( | 5120 | + | X | ) | × | 3 50 | = | X |
| Left side of the equation = | 5120 | × | 3 50 | + | X | × | 3 50 |
| = | 1536 5 | + | X | × | 3 50 |
1536 5 | + | 3 50 | X | = | X |
3 50 | X | − | X | = | - | 1536 5 |
| - | 47 50 | X | = | - | 1536 5 |
1536 5 | = | 47 50 | X |
47 50 | X | = | 1536 5 |
| X | = | 1536 5 | ÷ | 47 50 |
| = | 1536 5 | × | 50 47 |
| = | 1536 | × | 10 47 |
| X | = | 15360 47 |
| X | = | 326.808511 |
