57 100 | x | + | ( | 330 | − | x | ) | × | 29 100 | + | 17 50 | ( | x | − | 230 | ) | = | 1287 10 |
| Left side of the equation = | 57 100 | x | + | 330 | × | 29 100 | − | x | × | 29 100 | + | 17 50 | ( | x | − | 230 | ) |
| = | 57 100 | x | + | 957 10 | − | x | × | 29 100 | + | 17 50 | ( | x | − | 230 | ) |
| = | 7 25 | x | + | 957 10 | + | 17 50 | ( | x | − | 230 | ) |
| = | 7 25 | x | + | 957 10 | + | 17 50 | x | − | 17 50 | × | 230 |
| = | 7 25 | x | + | 957 10 | + | 17 50 | x | − | 391 5 |
| = | 31 50 | x | + | 35 2 |
31 50 | x | + | 35 2 | = | 1287 10 |
31 50 | x | = | 1287 10 | − | 35 2 |
31 50 | x | = | 556 5 |
| x | = | 556 5 | ÷ | 31 50 |
| = | 556 5 | × | 50 31 |
| = | 556 | × | 10 31 |
| x | = | 5560 31 |
| x | = | 179.354839 |
