| x | ÷ | ( | 1 20 | − | x | ) | = | 2 125 |
| Multiply both sides of the equation by: | ( | 1 20 | − | x | ) |
| x | = | 2 125 | ( | 1 20 | − | x | ) |
| x | = | 2 125 | × | 1 20 | − | 2 125 | x |
| x | = | 1 1250 | − | 2 125 | x |
| x | + | 2 125 | x | = | 1 1250 |
127 125 | x | = | 1 1250 |
| x | = | 1 1250 | ÷ | 127 125 |
| = | 1 1250 | × | 125 127 |
| = | 1 10 | × | 1 127 |
| x | = | 1 1270 |
| x | = | 0.000787 |
