| ( | ( | 329 | × | 9 | ) | + | ( | 10 | x | ) | ) | ÷ | ( | 329 | + | x | ) | = | 46 5 |
| Multiply both sides of the equation by: | ( | 329 | + | x | ) |
| ( | ( | 329 | × | 9 | ) | + | ( | 10 | x | ) | ) | = | 46 5 | ( | 329 | + | x | ) |
| ( | 329 | × | 9 | ) | + | ( | 10 | x | ) | = | 46 5 | ( | 329 | + | x | ) |
| ( | 329 | × | 9 | ) | + | ( | 10 | x | ) | = | 46 5 | × | 329 | + | 46 5 | x |
| ( | 329 | × | 9 | ) | + | ( | 10 | x | ) | = | 15134 5 | + | 46 5 | x |
| 329 | × | 9 | + | ( | 10 | x | ) | = | 15134 5 | + | 46 5 | x |
| 2961 | + | ( | 10 | x | ) | = | 15134 5 | + | 46 5 | x |
| 2961 | + | 10 | x | = | 15134 5 | + | 46 5 | x |
| 10 | x | − | 46 5 | x | = | 15134 5 | − | 2961 |
4 5 | x | = | 15134 5 | − | 2961 |
4 5 | x | = | 329 5 |
| x | = | 329 5 | ÷ | 4 5 |
| = | 329 5 | × | 5 4 |
| = | 329 | × | 1 4 |
| x | = | 329 4 |
| x | = | 82.25 |
