| a | ( | 11 | ÷ | 6 | − | 11 | ÷ | 12 | ) | + | 6 | ÷ | 5 | = | 23 | ÷ | 10 |
| Left side of the equation = | a | ( | 11 | ÷ | 6 | − | 11 | ÷ | 12 | ) | + | 6 5 |
| a | ( | 11 | ÷ | 6 | − | 11 | ÷ | 12 | ) | + | 6 5 | = | 23 | ÷ | 10 |
| Left side of the equation = | a | × | 11 | ÷ | 6 | − | a | × | 11 | ÷ | 12 | + | 6 5 |
| = | a | × | 11 6 | − | a | × | 11 12 | + | 6 5 |
| = | 11 12 | a | + | 6 5 |
11 12 | a | + | 6 5 | = | 23 | ÷ | 10 |
| Right side of the equation = | 23 10 |
11 12 | a | + | 6 5 | = | 23 10 |
11 12 | a | = | 23 10 | − | 6 5 |
11 12 | a | = | 11 10 |
| a | = | 11 10 | ÷ | 11 12 |
| = | 11 10 | × | 12 11 |
| = | 1 5 | × | 6 |
| a | = | 6 5 |
| a | = | 1.2 |
