| 25 | = | 1 | ( | 1 | + | g | ) | ÷ | ( | 43 500 | − | g | ) |
| Multiply both sides of the equation by: | ( | 43 500 | − | g | ) |
| 25 | ( | 43 500 | − | g | ) | = | 1 | ( | 1 | + | g | ) |
| 25 | × | 43 500 | − | 25 | g | = | 1 | ( | 1 | + | g | ) |
| 25 | × | 43 500 | − | 25 | g | = | 1 | × | 1 | + | 1 | g |
43 20 | − | 25 | g | = | 1 | + | 1 | g |
| - | 25 | g | − | 1 | g | = | 1 | − | 43 20 |
| - | 26 | g | = | 1 | − | 43 20 |
| - | 26 | g | = | - | 23 20 |
23 20 | = | 26 | g |
| 26 | g | = | 23 20 |
| g | = | 23 20 | ÷ | 26 |
| = | 23 20 | × | 1 26 |
| g | = | 23 520 |
| g | = | 0.044231 |
