| ( | 2 | X | − | 1 | ) | ÷ | 3 | = | 1 | − | ( | 3 | − | 2 | X | ) | ÷ | 5 |
| Left side of the equation = | 2 | X | × | 1 3 | − | 1 | × | 1 3 |
| = | 2 3 | X | − | 1 3 |
2 3 | X | − | 1 3 | = | 1 | − | ( | 3 | − | 2 | X | ) | ÷ | 5 |
| Right side of the equation = | 1 | − | 3 | × | 1 5 | + | 2 | X | × | 1 5 |
| = | 1 | − | 3 5 | + | 2 5 | X |
| = | 2 5 | + | 2 5 | X |
2 3 | X | − | 1 3 | = | 2 5 | + | 2 5 | X |
2 3 | X | − | 2 5 | X | = | 2 5 | + | 1 3 |
4 15 | X | = | 2 5 | + | 1 3 |
4 15 | X | = | 11 15 |
| X | = | 11 15 | ÷ | 4 15 |
| = | 11 15 | × | 15 4 |
| = | 11 | × | 1 4 |
| X | = | 11 4 |
| X | = | 2.75 |
