| ( | 1843 10 | + | 3 | x | ) | ÷ | ( | 519 5 | + | x | ) | = | 1 |
| Multiply both sides of the equation by: | ( | 519 5 | + | x | ) |
| ( | 1843 10 | + | 3 | x | ) | = | 1 | ( | 519 5 | + | x | ) |
1843 10 | + | 3 | x | = | 1 | ( | 519 5 | + | x | ) |
1843 10 | + | 3 | x | = | 1 | × | 519 5 | + | 1 | x |
1843 10 | + | 3 | x | = | 519 5 | + | 1 | x |
| 3 | x | − | 1 | x | = | 519 5 | − | 1843 10 |
| 2 | x | = | 519 5 | − | 1843 10 |
| 2 | x | = | - | 161 2 |
| x | = | - | 161 2 | ÷ | 2 |
| = | - | 161 2 | × | 1 2 |
| x | = | - | 161 4 |
| x | = | - 40.25 |
