| 6 | ( | 86 5 | − | x | ) | = | 265 | ( | x | + | 58 5 | ) |
| Left side of the equation = | 6 | × | 86 5 | − | 6 | x |
| = | 516 5 | − | 6 | x |
516 5 | − | 6 | x | = | 265 | ( | x | + | 58 5 | ) |
| Right side of the equation = | 265 | x | + | 265 | × | 58 5 |
| = | 265 | x | + | 3074 |
516 5 | − | 6 | x | = | 265 | x | + | 3074 |
| - | 6 | x | − | 265 | x | = | 3074 | − | 516 5 |
| - | 271 | x | = | 3074 | − | 516 5 |
| - | 271 | x | = | 14854 5 |
| - | 14854 5 | = | 271 | x |
| 271 | x | = | - | 14854 5 |
| x | = | - | 14854 5 | ÷ | 271 |
| = | - | 14854 5 | × | 1 271 |
| x | = | - | 14854 1355 |
| x | = | - 10.962362 |
