| ( | 175 | + | x | ) | ÷ | ( | 363 | + | x | + | x | ) | = | 1 2 |
| Multiply both sides of the equation by: | ( | 363 | + | x | + | x | ) |
| ( | 175 | + | x | ) | = | 1 2 | ( | 363 | + | x | + | x | ) |
| 175 | + | x | = | 1 2 | ( | 363 | + | x | + | x | ) |
| 175 | + | x | = | 1 2 | × | 363 | + | 1 2 | x | + | 1 2 | x |
| 175 | + | x | = | 363 2 | + | 1 2 | x | + | 1 2 | x |
| 175 | + | x | = | 363 2 | + | 1 | x |
| x | − | 1 | x | = | 363 2 | − | 175 |
| 0 | x | = | 363 2 | − | 175 |
| 0 | x | = | 13 2 |
