| ( | 5 | x | + | 16839 | ) | ÷ | ( | x | + | 3670 | ) | = | 23 5 |
| Multiply both sides of the equation by: | ( | x | + | 3670 | ) |
| ( | 5 | x | + | 16839 | ) | = | 23 5 | ( | x | + | 3670 | ) |
| 5 | x | + | 16839 | = | 23 5 | ( | x | + | 3670 | ) |
| 5 | x | + | 16839 | = | 23 5 | x | + | 23 5 | × | 3670 |
| 5 | x | + | 16839 | = | 23 5 | x | + | 16882 |
| 5 | x | − | 23 5 | x | = | 16882 | − | 16839 |
2 5 | x | = | 16882 | − | 16839 |
2 5 | x | = | 43 |
| x | = | 43 | ÷ | 2 5 |
| = | 43 | × | 5 2 |
| x | = | 215 2 |
| x | = | 107.5 |
