| 1 | ÷ | x | + | 9 10 | ( | - | 6 5 | ) | ÷ | 131 50 | = | 0 |
| Multiply both sides of the equation by: | x |
| 1 | + | 9 10 | ( | - | 6 5 | ) | ÷ | 131 50 | × | x | = | 0 |
| 1 | − | 9 10 | × | 6 5 | ÷ | 131 50 | × | x | = | 0 |
| 1 | − | 54 131 | x | = | 0 |
| - | 54 131 | x | = | 0 | − | 1 |
| - | 54 131 | x | = | - | 1 |
| 1 | = | 54 131 | x |
54 131 | x | = | 1 |
| x | = | 1 | ÷ | 54 131 |
| = | 1 | × | 131 54 |
| x | = | 131 54 |
| x | = | 2.425926 |
