( | x | + | 1 | ) | ÷ | 2 | + | ( | x | + | 2 | ) | ÷ | 3 | = | x |
Left side of the equation = | x | × | 1 2 | + | 1 | × | 1 2 | + | ( | x | + | 2 | ) | × | 1 3 |
= | x | × | 1 2 | + | 1 2 | + | ( | x | + | 2 | ) | × | 1 3 |
= | 1 2 | x | + | 1 2 | + | x | × | 1 3 | + | 2 | × | 1 3 |
= | 1 2 | x | + | 1 2 | + | x | × | 1 3 | + | 2 3 |
= | 5 6 | x | + | 7 6 |
5 6 | x | + | 7 6 | = | x |
5 6 | x | − | x | = | - | 7 6 |
- | 1 6 | x | = | - | 7 6 |
7 6 | = | 1 6 | x |
1 6 | x | = | 7 6 |
x | = | 7 6 | ÷ | 1 6 |
= | 7 6 | × | 6 |
= | 7 | × | 1 |
x | = | 7 |
