29 20 | = | 120 | ÷ | ( | 120 | − | T | ) |
| Multiply both sides of the equation by: | ( | 120 | − | T | ) |
29 20 | ( | 120 | − | T | ) | = | 120 |
29 20 | × | 120 | − | 29 20 | T | = | 120 |
| 174 | − | 29 20 | T | = | 120 |
| - | 29 20 | T | = | 120 | − | 174 |
| - | 29 20 | T | = | - | 54 |
| 54 | = | 29 20 | T |
29 20 | T | = | 54 |
| T | = | 54 | ÷ | 29 20 |
| = | 54 | × | 20 29 |
| T | = | 1080 29 |
| T | = | 37.241379 |
