| ( | 6142 | − | X | ) | ÷ | 6142 | × | 100 | = | 1 2 |
| Left side of the equation = | ( | 6142 | − | X | ) | × | 50 3071 |
| ( | 6142 | − | X | ) | × | 50 3071 | = | 1 2 |
| Left side of the equation = | 6142 | × | 50 3071 | − | X | × | 50 3071 |
| = | 100 | − | X | × | 50 3071 |
| 100 | − | 50 3071 | X | = | 1 2 |
| - | 50 3071 | X | = | 1 2 | − | 100 |
| - | 50 3071 | X | = | - | 199 2 |
