| x | ÷ | 53 | + | ( | 169 500 | − | x | ) | ÷ | 84 | = | 21 4000 |
| Left side of the equation = | 1 53 | x | + | 169 500 | × | 1 84 | − | x | × | 1 84 |
| = | 1 53 | x | + | 169 42000 | − | x | × | 1 84 |
| = | 31 4452 | x | + | 169 42000 |
31 4452 | x | + | 169 42000 | = | 21 4000 |
31 4452 | x | = | 21 4000 | − | 169 42000 |
31 4452 | x | = | 103 84000 |
| x | = | 103 84000 | ÷ | 31 4452 |
| = | 103 84000 | × | 4452 31 |
| = | 103 1000 | × | 53 31 |
| x | = | 5459 31000 |
| x | = | 0.176097 |
