| ( | x | − | 163 1000 | ) | ÷ | ( | 97 500 | − | 163 1000 | ) | × | 100 | = | 50 |
| Multiply both sides of the equation by: | ( | 97 500 | − | 163 1000 | ) |
| ( | x | − | 163 1000 | ) | × | 100 | = | 50 | ( | 97 500 | − | 163 1000 | ) |
| x | × | 100 | − | 163 1000 | × | 100 | = | 50 | ( | 97 500 | − | 163 1000 | ) |
| x | × | 100 | − | 163 1000 | × | 100 | = | 50 | × | 97 500 | − | 50 | × | 163 1000 |
| x | × | 100 | − | 163 10 | = | 97 10 | − | 163 20 |
| 100 | x | − | 163 10 | = | 31 20 |
| 100 | x | = | 31 20 | + | 163 10 |
| 100 | x | = | 357 20 |
| x | = | 357 20 | ÷ | 100 |
| = | 357 20 | × | 1 100 |
| x | = | 357 2000 |
| x | = | 0.1785 |
