| 10000 | ( | 3 5 | t | + | 16 | ) | − | ( | 160000 | + | 600 | t | ) | = | 108000 |
| Left side of the equation = | 10000 | × | 3 5 | t | + | 10000 | × | 16 | − | ( | 160000 | + | 600 | t | ) |
| = | 6000 | t | + | 160000 | − | ( | 160000 | + | 600 | t | ) |
| = | 6000 | t | + | 160000 | − | 160000 | − | 600 | t |
| = | 5400 | t | + | 0 |
| 5400 | t | + | 0 | = | 108000 |
| t | = | 108000 | ÷ | 5400 |
| = | 108000 | × | 1 5400 |
| = | 20 | × | 1 |
| t | = | 20 |
