| 22 | × | 23 10 | + | ( | 26 | − | 22 | ) | a | = | 322 5 |
| Left side of the equation = | 253 5 | + | ( | 26 | − | 22 | ) | a |
253 5 | + | ( | 26 | − | 22 | ) | a | = | 322 5 |
| Left side of the equation = | 253 5 | + | 26 | a | − | 22 | a |
| = | 253 5 | + | 4 | a |
253 5 | + | 4 | a | = | 322 5 |
| 4 | a | = | 322 5 | − | 253 5 |
| 4 | a | = | 69 5 |
| a | = | 69 5 | ÷ | 4 |
| = | 69 5 | × | 1 4 |
| a | = | 69 20 |
| a | = | 3.45 |
