7 2 | x | + | 11 2 | ( | 4217 | − | x | ) | = | 44131 2 |
| Left side of the equation = | 7 2 | x | + | 11 2 | × | 4217 | − | 11 2 | x |
| = | 7 2 | x | + | 46387 2 | − | 11 2 | x |
| = | - | 2 | x | + | 46387 2 |
| - | 2 | x | + | 46387 2 | = | 44131 2 |
| - | 2 | x | = | 44131 2 | − | 46387 2 |
| - | 2 | x | = | - | 1128 |
| 1128 | = | 2 | x |
| 2 | x | = | 1128 |
| x | = | 1128 | ÷ | 2 |
| = | 1128 | × | 1 2 |
| = | 564 | × | 1 |
| x | = | 564 |
