| 50000 | ÷ | x | × | 20000 | = | 86 |
| Multiply both sides of the equation by: | x |
| 50000 | × | 20000 | = | 86 | x |
| - | 86 | x | = | - | 50000 | × | 20000 |
| - | 86 | x | = | - | 1000000000 |
| 1000000000 | = | 86 | x |
| 86 | x | = | 1000000000 |
| x | = | 1000000000 | ÷ | 86 |
| = | 1000000000 | × | 1 86 |
| = | 500000000 | × | 1 43 |
| x | = | 500000000 43 |
| x | = | 11627906.976744 |
