3 20 | ÷ | ( | x | − | 5 | ) | ÷ | 5 | = | 3 10 |
| Multiply both sides of the equation by: | ( | x | − | 5 | ) |
3 20 | ÷ | 5 | = | 3 10 | ( | x | − | 5 | ) |
3 20 | ÷ | 5 | = | 3 10 | x | − | 3 10 | × | 5 |
3 100 | = | 3 10 | x | − | 3 2 |
| - | 3 10 | x | = | - | 3 2 | − | 3 100 |
| - | 3 10 | x | = | - | 153 100 |
153 100 | = | 3 10 | x |
3 10 | x | = | 153 100 |
| x | = | 153 100 | ÷ | 3 10 |
| = | 153 100 | × | 10 3 |
| = | 51 10 | × | 1 |
| x | = | 51 10 |
| x | = | 5.1 |
