| ( | 178 | × | 449 1000 | + | x | ) | ÷ | ( | 178 | + | x | ) | = | 3 5 |
| Multiply both sides of the equation by: | ( | 178 | + | x | ) |
| ( | 178 | × | 449 1000 | + | x | ) | = | 3 5 | ( | 178 | + | x | ) |
| 178 | × | 449 1000 | + | x | = | 3 5 | ( | 178 | + | x | ) |
| 178 | × | 449 1000 | + | x | = | 3 5 | × | 178 | + | 3 5 | x |
39961 500 | + | x | = | 534 5 | + | 3 5 | x |
| x | − | 3 5 | x | = | 534 5 | − | 39961 500 |
2 5 | x | = | 534 5 | − | 39961 500 |
2 5 | x | = | 13439 500 |
| x | = | 13439 500 | ÷ | 2 5 |
| = | 13439 500 | × | 5 2 |
| = | 13439 100 | × | 1 2 |
| x | = | 13439 200 |
| x | = | 67.195 |
