| X | ÷ | 77 | − | X | ÷ | 76 | = | 1 | ÷ | 3600 |
| Left side of the equation = | - | 1 5852 | X |
| - | 1 5852 | X | = | 1 | ÷ | 3600 |
| Right side of the equation = | 1 3600 |
| - | 1 5852 | X | = | 1 3600 |
| - | 1 3600 | = | 1 5852 | X |
1 5852 | X | = | - | 1 3600 |
| X | = | - | 1 3600 | ÷ | 1 5852 |
| = | - | 1 3600 | × | 5852 |
| = | - | 1 900 | × | 1463 |
| X | = | - | 1463 900 |
| X | = | - 1.625556 |
