| 1 | − | 2 | y | − | 5 | ÷ | 6 | = | 3 | − | y | ÷ | 4 |
| Left side of the equation = | 1 | − | 2 | y | − | 5 6 |
| = | 1 6 | − | 2 | y |
1 6 | − | 2 | y | = | 3 | − | y | ÷ | 4 |
| - | 2 | y | + | 1 4 | y | = | 3 | − | 1 6 |
| - | 7 4 | y | = | 3 | − | 1 6 |
| - | 7 4 | y | = | 17 6 |
| - | 17 6 | = | 7 4 | y |
7 4 | y | = | - | 17 6 |
| y | = | - | 17 6 | ÷ | 7 4 |
| = | - | 17 6 | × | 4 7 |
| = | - | 17 3 | × | 2 7 |
| y | = | - | 34 21 |
| y | = | - 1.619048 |
