9 20 | − | ( | ( | 1 | + | G | ) | ÷ | G | ) | × | 1 20 | = | 0 |
9 20 | − | ( | 1 | + | G | ) | ÷ | G | × | 1 20 | = | 0 |
| Multiply both sides of the equation by: | G |
9 20 | G | − | ( | 1 | + | G | ) | × | 1 20 | = | 0 |
9 20 | G | − | 1 | × | 1 20 | − | G | × | 1 20 | = | 0 |
9 20 | G | − | 1 20 | − | G | × | 1 20 | = | 0 |
2 5 | G | − | 1 20 | = | 0 |
2 5 | G | = | 0 | + | 1 20 |
2 5 | G | = | 1 20 |
| G | = | 1 20 | ÷ | 2 5 |
| = | 1 20 | × | 5 2 |
| = | 1 4 | × | 1 2 |
| G | = | 1 8 |
| G | = | 0.125 |
