49 10 | = | 10000 | ÷ | ( | 10000 | + | x | ) | × | 54 5 |
| Multiply both sides of the equation by: | ( | 10000 | + | x | ) |
49 10 | ( | 10000 | + | x | ) | = | 10000 | × | 54 5 |
49 10 | × | 10000 | + | 49 10 | x | = | 10000 | × | 54 5 |
| 49000 | + | 49 10 | x | = | 108000 |
49 10 | x | = | 108000 | − | 49000 |
49 10 | x | = | 59000 |
| x | = | 59000 | ÷ | 49 10 |
| = | 59000 | × | 10 49 |
| x | = | 590000 49 |
