| 8 | X | − | 24 | ÷ | 25 | × | X | − | 40 | = | 4 | ÷ | 1 |
| Left side of the equation = | 8 | X | − | 24 25 | X | − | 40 |
| = | 176 25 | X | − | 40 |
176 25 | X | − | 40 | = | 4 | ÷ | 1 |
| Right side of the equation = | 4 |
176 25 | X | − | 40 | = | 4 |
176 25 | X | = | 4 | + | 40 |
176 25 | X | = | 44 |
| X | = | 44 | ÷ | 176 25 |
| = | 44 | × | 25 176 |
| = | 1 | × | 25 4 |
| X | = | 25 4 |
| X | = | 6.25 |
