| 1 | ÷ | x | + | 4 | + | 1 | ÷ | x | = | 1 | ÷ | 10 |
| Multiply both sides of the equation by: | x |
| 1 | + | 4 | x | + | 1 | ÷ | 1 | × | 1 | = | 1 | ÷ | 10 | × | x |
| 4 | x | − | 1 | ÷ | 10 | × | x | = | - | 1 | − | 1 | ÷ | 1 | × | 1 |
| 4 | x | − | 1 10 | x | = | - | 1 | − | 1 | ÷ | 1 | × | 1 |
| 4 | x | − | 1 10 | x | = | - | 1 | − | 1 |
39 10 | x | = | - | 1 | − | 1 |
39 10 | x | = | - | 2 |
| x | = | - | 2 | ÷ | 39 10 |
| = | - | 2 | × | 10 39 |
| x | = | - | 20 39 |
| x | = | - 0.512821 |
