| ( | 2 | + | 4 | t | ) | − | ( | 8 | + | t | ) | = | ( | 10 | + | 2 | t | ) | − | ( | 2 | + | 4 | t | ) |
| Left side of the equation = | 2 | + | 4 | t | − | ( | 8 | + | t | ) |
| = | 2 | + | 4 | t | − | 8 | − | t |
| = | - | 6 | + | 3 | t |
| - | 6 | + | 3 | t | = | ( | 10 | + | 2 | t | ) | − | ( | 2 | + | 4 | t | ) |
| Right side of the equation = | 10 | + | 2 | t | − | ( | 2 | + | 4 | t | ) |
| = | 10 | + | 2 | t | − | 2 | − | 4 | t |
| = | 8 | − | 2 | t |
| - | 6 | + | 3 | t | = | 8 | − | 2 | t |
| 3 | t | + | 2 | t | = | 8 | + | 6 |
| 5 | t | = | 8 | + | 6 |
| 5 | t | = | 14 |
| t | = | 14 | ÷ | 5 |
| = | 14 | × | 1 5 |
| t | = | 14 5 |
| t | = | 2.8 |
