( | 3 | y | − | 7 | ) | ÷ | 4 | − | 1 | = | ( | 5 | y | − | 1 | ) | ÷ | 6 |
Left side of the equation = | 3 | y | × | 1 4 | − | 7 | × | 1 4 | − | 1 |
= | 3 4 | y | − | 7 4 | − | 1 |
= | 3 4 | y | − | 11 4 |
3 4 | y | − | 11 4 | = | ( | 5 | y | − | 1 | ) | ÷ | 6 |
Right side of the equation = | 5 | y | × | 1 6 | − | 1 | × | 1 6 |
= | 5 6 | y | − | 1 6 |
3 4 | y | − | 11 4 | = | 5 6 | y | − | 1 6 |
3 4 | y | − | 5 6 | y | = | - | 1 6 | + | 11 4 |
- | 1 12 | y | = | - | 1 6 | + | 11 4 |
- | 1 12 | y | = | 31 12 |
- | 31 12 | = | 1 12 | y |
1 12 | y | = | - | 31 12 |
y | = | - | 31 12 | ÷ | 1 12 |
= | - | 31 12 | × | 12 |
= | - | 31 | × | 1 |
y | = | - | 31 |
