| 240 | x | = | 431 2 | ( | 27 | + | 259 10 | + | x | ) |
| Right side of the equation = | 431 2 | × | 27 | + | 431 2 | × | 259 10 | + | 431 2 | x |
| = | 11637 2 | + | 111629 20 | + | 431 2 | x |
| = | 227999 20 | + | 431 2 | x |
| 240 | x | = | 227999 20 | + | 431 2 | x |
| 240 | x | − | 431 2 | x | = | 227999 20 |
49 2 | x | = | 227999 20 |
| x | = | 227999 20 | ÷ | 49 2 |
| = | 227999 20 | × | 2 49 |
| = | 227999 10 | × | 1 49 |
| x | = | 227999 490 |
| x | = | 465.304082 |
