| 4 | ( | t | − | 41 | ) | = | 1 | ( | 55 | − | t | ) |
| Left side of the equation = | 4 | t | − | 4 | × | 41 |
| = | 4 | t | − | 164 |
| 4 | t | − | 164 | = | 1 | ( | 55 | − | t | ) |
| Right side of the equation = | 1 | × | 55 | − | 1 | t |
| = | 55 | − | 1 | t |
| 4 | t | − | 164 | = | 55 | − | 1 | t |
| 4 | t | + | 1 | t | = | 55 | + | 164 |
| 5 | t | = | 55 | + | 164 |
| 5 | t | = | 219 |
| t | = | 219 | ÷ | 5 |
| = | 219 | × | 1 5 |
| t | = | 219 5 |
| t | = | 43.8 |
