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