( | 2 | − | a | ) | ÷ | 3 | − | ( | 1 | − | a | ) | ÷ | 2 | = | 0 |
Left side of the equation = | 2 | × | 1 3 | − | a | × | 1 3 | − | ( | 1 | − | a | ) | × | 1 2 |
= | 2 3 | − | a | × | 1 3 | − | ( | 1 | − | a | ) | × | 1 2 |
= | 2 3 | − | 1 3 | a | − | 1 | × | 1 2 | + | a | × | 1 2 |
= | 2 3 | − | 1 3 | a | − | 1 2 | + | a | × | 1 2 |
= | 1 6 | + | 1 6 | a |
1 6 | + | 1 6 | a | = | 0 |
1 6 | a | = | 0 | − | 1 6 |
1 6 | a | = | - | 1 6 |
a | = | - | 1 6 | ÷ | 1 6 |
= | - | 1 6 | × | 6 |
= | - | 1 | × | 1 |
a | = | - | 1 |
