( | x | + | 3 | ) | ÷ | 1 2 | + | ( | ( | 1 | ÷ | 3 | ) | ( | x | + | 4 | ) | ) | ÷ | 1 8 | − | 5 | x | = | 19 |
Left side of the equation = | x | × | 2 | + | 3 | × | 2 | + | ( | ( | 1 | ÷ | 3 | ) | ( | x | + | 4 | ) | ) | × | 8 | − | 5 | x |
= | x | × | 2 | + | 6 | + | ( | ( | 1 | ÷ | 3 | ) | ( | x | + | 4 | ) | ) | × | 8 | − | 5 | x |
= | - | 3 | x | + | 6 | + | ( | ( | 1 | ÷ | 3 | ) | ( | x | + | 4 | ) | ) | × | 8 |
= | - | 3 | x | + | 6 | + | ( | 1 | ÷ | 3 | ) | ( | x | + | 4 | ) | × | 8 |
= | - | 3 | x | + | 6 | + | 1 | ÷ | 3 | × | ( | x | + | 4 | ) | × | 8 |
= | - | 3 | x | + | 6 | + | 8 3 | ( | x | + | 4 | ) |
= | - | 3 | x | + | 6 | + | 8 3 | x | + | 8 3 | × | 4 |
= | - | 3 | x | + | 6 | + | 8 3 | x | + | 32 3 |
= | - | 1 3 | x | + | 50 3 |
- | 1 3 | x | + | 50 3 | = | 19 |
- | 1 3 | x | = | 19 | − | 50 3 |
- | 1 3 | x | = | 7 3 |
- | 7 3 | = | 1 3 | x |
1 3 | x | = | - | 7 3 |
x | = | - | 7 3 | ÷ | 1 3 |
= | - | 7 3 | × | 3 |
= | - | 7 | × | 1 |
x | = | - | 7 |
