| - | 2 | ÷ | 3 | + | 2 | g | = | - | 3 | ÷ | 2 | × | g | + | 3 | − | 2 | g |
| Left side of the equation = | - | 2 3 | + | 2 | g |
| - | 2 3 | + | 2 | g | = | - | 3 | ÷ | 2 | × | g | + | 3 | − | 2 | g |
| Right side of the equation = | - | 3 2 | g | + | 3 | − | 2 | g |
| = | - | 7 2 | g | + | 3 |
| - | 2 3 | + | 2 | g | = | - | 7 2 | g | + | 3 |
| 2 | g | + | 7 2 | g | = | 3 | + | 2 3 |
11 2 | g | = | 3 | + | 2 3 |
11 2 | g | = | 11 3 |
| g | = | 11 3 | ÷ | 11 2 |
| = | 11 3 | × | 2 11 |
| = | 1 3 | × | 2 |
| g | = | 2 3 |
| g | = | 0.666667 |
