| x | ÷ | ( | x | + | 50 | ) | = | 3 10000 |
| Multiply both sides of the equation by: | ( | x | + | 50 | ) |
| x | = | 3 10000 | ( | x | + | 50 | ) |
| x | = | 3 10000 | x | + | 3 10000 | × | 50 |
| x | = | 3 10000 | x | + | 3 200 |
| x | − | 3 10000 | x | = | 3 200 |
9997 10000 | x | = | 3 200 |
| x | = | 3 200 | ÷ | 9997 10000 |
| = | 3 200 | × | 10000 9997 |
| = | 3 | × | 50 9997 |
| x | = | 150 9997 |
| x | = | 0.015005 |
