| ( | 3 | Y | + | 1 | ) | ÷ | 4 | = | 2 | − | ( | 2 | Y | − | 1 | ) | ÷ | 3 |
| Left side of the equation = | 3 | Y | × | 1 4 | + | 1 | × | 1 4 |
| = | 3 4 | Y | + | 1 4 |
3 4 | Y | + | 1 4 | = | 2 | − | ( | 2 | Y | − | 1 | ) | ÷ | 3 |
| Right side of the equation = | 2 | − | 2 | Y | × | 1 3 | + | 1 | × | 1 3 |
| = | 2 | − | 2 3 | Y | + | 1 3 |
| = | 7 3 | − | 2 3 | Y |
3 4 | Y | + | 1 4 | = | 7 3 | − | 2 3 | Y |
3 4 | Y | + | 2 3 | Y | = | 7 3 | − | 1 4 |
17 12 | Y | = | 7 3 | − | 1 4 |
17 12 | Y | = | 25 12 |
| Y | = | 25 12 | ÷ | 17 12 |
| = | 25 12 | × | 12 17 |
| = | 25 | × | 1 17 |
| Y | = | 25 17 |
| Y | = | 1.470588 |
