31 2 | ( | 1 | − | 2 | x | ) | × | 2 | = | x | × | 2 |
| Left side of the equation = | 31 | ( | 1 | − | 2 | x | ) |
| 31 | ( | 1 | − | 2 | x | ) | = | x | × | 2 |
| Left side of the equation = | 31 | × | 1 | − | 31 | × | 2 | x |
| = | 31 | − | 62 | x |
| 31 | − | 62 | x | = | x | × | 2 |
| - | 62 | x | − | 2 | x | = | - | 31 |
| - | 64 | x | = | - | 31 |
| 31 | = | 64 | x |
| 64 | x | = | 31 |
| x | = | 31 | ÷ | 64 |
| = | 31 | × | 1 64 |
| x | = | 31 64 |
| x | = | 0.484375 |
