| ( | ( | 35700 | − | X | ) | ÷ | 51 | ) | × | 2 | = | ( | 181300 | − | X | ) | ÷ | 259 |
| Left side of the equation = | ( | 35700 | − | X | ) | ÷ | 51 | × | 2 |
| = | ( | 35700 | − | X | ) | × | 2 51 |
| = | 35700 | × | 2 51 | − | X | × | 2 51 |
| = | 1400 | − | X | × | 2 51 |
| 1400 | − | 2 51 | X | = | ( | 181300 | − | X | ) | ÷ | 259 |
| Right side of the equation = | 181300 | × | 1 259 | − | X | × | 1 259 |
| = | 700 | − | X | × | 1 259 |
| 1400 | − | 2 51 | X | = | 700 | − | 1 259 | X |
