13 500 | = | 49 20 | x | ÷ | ( | 1 | + | 29 20 | x | ) |
| Multiply both sides of the equation by: | ( | 1 | + | 29 20 | x | ) |
13 500 | ( | 1 | + | 29 20 | x | ) | = | 49 20 | x |
13 500 | × | 1 | + | 13 500 | × | 29 20 | x | = | 49 20 | x |
13 500 | + | 377 10000 | x | = | 49 20 | x |
377 10000 | x | − | 49 20 | x | = | - | 13 500 |
| - | 24123 10000 | x | = | - | 13 500 |
13 500 | = | 24123 10000 | x |
24123 10000 | x | = | 13 500 |
| x | = | 13 500 | ÷ | 24123 10000 |
| = | 13 500 | × | 10000 24123 |
| = | 13 | × | 20 24123 |
| x | = | 260 24123 |
| x | = | 0.010778 |
