| ( | 168 | + | x | ) | ÷ | ( | 48 | + | 200 | − | x | ) | = | 17 8 |
| Multiply both sides of the equation by: | ( | 48 | + | 200 | − | x | ) |
| ( | 168 | + | x | ) | = | 17 8 | ( | 48 | + | 200 | − | x | ) |
| 168 | + | x | = | 17 8 | ( | 48 | + | 200 | − | x | ) |
| 168 | + | x | = | 17 8 | × | 48 | + | 17 8 | × | 200 | − | 17 8 | x |
| 168 | + | x | = | 102 | + | 425 | − | 17 8 | x |
| 168 | + | x | = | 527 | − | 17 8 | x |
| x | + | 17 8 | x | = | 527 | − | 168 |
25 8 | x | = | 527 | − | 168 |
25 8 | x | = | 359 |
| x | = | 359 | ÷ | 25 8 |
| = | 359 | × | 8 25 |
| x | = | 2872 25 |
| x | = | 114.88 |
