| 10 | ( | 80 | − | t | ) | = | 14 | ( | t | − | 56 | ) |
| Left side of the equation = | 10 | × | 80 | − | 10 | t |
| = | 800 | − | 10 | t |
| 800 | − | 10 | t | = | 14 | ( | t | − | 56 | ) |
| Right side of the equation = | 14 | t | − | 14 | × | 56 |
| = | 14 | t | − | 784 |
| 800 | − | 10 | t | = | 14 | t | − | 784 |
| - | 10 | t | − | 14 | t | = | - | 784 | − | 800 |
| - | 24 | t | = | - | 784 | − | 800 |
| - | 24 | t | = | - | 1584 |
| 1584 | = | 24 | t |
| 24 | t | = | 1584 |
| t | = | 1584 | ÷ | 24 |
| = | 1584 | × | 1 24 |
| = | 66 | × | 1 |
| t | = | 66 |
