( | t | + | 2 | ) | ( | - | ( | t | ÷ | 3 | ) | + | 6 | ) | = | 6 | t |
Left side of the equation = | t | ( | - | ( | t | ÷ | 3 | ) | + | 6 | ) | + | 2 | ( | - | ( | t | ÷ | 3 | ) | + | 6 | ) |
= | - | t | ( | t | ÷ | 3 | ) | + | t | × | 6 | + | 2 | ( | - | ( | t | ÷ | 3 | ) | + | 6 | ) |
= | - | t | t | ÷ | 3 | + | 6 | t | + | 2 | ( | - | ( | t | ÷ | 3 | ) | + | 6 | ) |
= | - | t | t | × | 1 3 | + | 6 | t | − | 2 | ( | t | ÷ | 3 | ) | + | 2 | × | 6 |
= | - | t | t | × | 1 3 | + | 6 | t | − | 2 | ( | t | ÷ | 3 | ) | + | 12 |
= | - | t | t | × | 1 3 | + | 6 | t | − | 2 | t | ÷ | 3 | + | 12 |
= | - | t | t | × | 1 3 | + | 6 | t | − | 2 3 | t | + | 12 |
= | - | t | t | × | 1 3 | + | 16 3 | t | + | 12 |
- | t | t | × | 1 3 | + | 16 3 | t | + | 12 | = | 6 | t |
