67 10 | = | 24 | A | ÷ | ( | 80 | + | A | ) |
| Multiply both sides of the equation by: | ( | 80 | + | A | ) |
67 10 | ( | 80 | + | A | ) | = | 24 | A |
67 10 | × | 80 | + | 67 10 | A | = | 24 | A |
| 536 | + | 67 10 | A | = | 24 | A |
67 10 | A | − | 24 | A | = | - | 536 |
| - | 173 10 | A | = | - | 536 |
| 536 | = | 173 10 | A |
173 10 | A | = | 536 |
| A | = | 536 | ÷ | 173 10 |
| = | 536 | × | 10 173 |
| A | = | 5360 173 |
| A | = | 30.982659 |
