| x | ÷ | ( | x | + | ( | 1 | − | x | ) | × | 851 1000 | ) | = | 87 100 |
| Multiply both sides of the equation by: | ( | x | + | ( | 1 | − | x | ) | × | 851 1000 | ) |
| x | = | 87 100 | ( | x | + | ( | 1 | − | x | ) | × | 851 1000 | ) |
| x | = | 87 100 | x | + | 87 100 | ( | 1 | − | x | ) | × | 851 1000 |
| x | = | 87 100 | x | + | 74037 100000 | ( | 1 | − | x | ) |
| x | = | 87 100 | x | + | 74037 100000 | × | 1 | − | 74037 100000 | x |
| x | = | 87 100 | x | + | 74037 100000 | − | 74037 100000 | x |
| x | = | 12963 100000 | x | + | 74037 100000 |
| x | − | 12963 100000 | x | = | 74037 100000 |
87037 100000 | x | = | 74037 100000 |
| x | = | 74037 100000 | ÷ | 87037 100000 |
| = | 74037 100000 | × | 100000 87037 |
| = | 74037 | × | 1 87037 |
| x | = | 74037 87037 |
| x | = | 0.850638 |
