| 10000 | = | ( | X | × | 40 100 | × | 60 | ) | + | ( | X | × | 30 | ) |
| Right side of the equation = | X | × | 40 100 | × | 60 | + | ( | X | × | 30 | ) |
| = | X | × | 24 | + | ( | X | × | 30 | ) |
| = | 24 | X | + | X | × | 30 |
| = | 54 | X |
| 10000 | = | 54 | X |
| - | 54 | X | = | - | 10000 |
| 10000 | = | 54 | X |
| 54 | X | = | 10000 |
| X | = | 10000 | ÷ | 54 |
| = | 10000 | × | 1 54 |
| = | 5000 | × | 1 27 |
| X | = | 5000 27 |
| X | = | 185.185185 |
