| x | ÷ | ( | x | + | 4500 | ) | = | 1 | ÷ | 100 |
| Multiply both sides of the equation by: | ( | x | + | 4500 | ) |
| x | = | 1 | ÷ | 100 | × | ( | x | + | 4500 | ) |
| x | = | 1 | ÷ | 100 | × | x | + | 1 | ÷ | 100 | × | 4500 |
| x | = | 1 100 | x | + | 45 |
| x | − | 1 100 | x | = | 45 |
99 100 | x | = | 45 |
| x | = | 45 | ÷ | 99 100 |
| = | 45 | × | 100 99 |
| = | 5 | × | 100 11 |
| x | = | 500 11 |
| x | = | 45.454545 |
