| 16 | ( | t | − | 56 | ) | = | 12 | ( | 80 | − | t | ) |
| Left side of the equation = | 16 | t | − | 16 | × | 56 |
| = | 16 | t | − | 896 |
| 16 | t | − | 896 | = | 12 | ( | 80 | − | t | ) |
| Right side of the equation = | 12 | × | 80 | − | 12 | t |
| = | 960 | − | 12 | t |
| 16 | t | − | 896 | = | 960 | − | 12 | t |
| 16 | t | + | 12 | t | = | 960 | + | 896 |
| 28 | t | = | 960 | + | 896 |
| 28 | t | = | 1856 |
| t | = | 1856 | ÷ | 28 |
| = | 1856 | × | 1 28 |
| = | 464 | × | 1 7 |
| t | = | 464 7 |
| t | = | 66.285714 |
