| 1 | ÷ | x | + | ( | 1 | ÷ | x | × | 1 20 | ) | = | 3 2 |
| Multiply both sides of the equation by: | x |
| 1 | + | ( | 1 | ÷ | 1 | × | 1 20 | ) | × | 1 | = | 3 2 | x |
| 1 | + | 1 | ÷ | 1 | × | 1 20 | × | 1 | = | 3 2 | x |
| 1 | + | 1 20 | = | 3 2 | x |
21 20 | = | 3 2 | x |
| - | 3 2 | x | = | - | 21 20 |
21 20 | = | 3 2 | x |
3 2 | x | = | 21 20 |
| x | = | 21 20 | ÷ | 3 2 |
| = | 21 20 | × | 2 3 |
| = | 7 10 | × | 1 |
| x | = | 7 10 |
| x | = | 0.7 |
