| ( | 106 | × | 519 1000 | + | x | ) | ÷ | ( | 106 | + | x | ) | = | 3 5 |
| Multiply both sides of the equation by: | ( | 106 | + | x | ) |
| ( | 106 | × | 519 1000 | + | x | ) | = | 3 5 | ( | 106 | + | x | ) |
| 106 | × | 519 1000 | + | x | = | 3 5 | ( | 106 | + | x | ) |
| 106 | × | 519 1000 | + | x | = | 3 5 | × | 106 | + | 3 5 | x |
27507 500 | + | x | = | 318 5 | + | 3 5 | x |
| x | − | 3 5 | x | = | 318 5 | − | 27507 500 |
2 5 | x | = | 318 5 | − | 27507 500 |
2 5 | x | = | 4293 500 |
| x | = | 4293 500 | ÷ | 2 5 |
| = | 4293 500 | × | 5 2 |
| = | 4293 100 | × | 1 2 |
| x | = | 4293 200 |
| x | = | 21.465 |
