| 50000 | ÷ | x | + | 110000 | ÷ | ( | x | + | 60 | ) | = | 850 |
| Multiply both sides of the equation by: | x |
| 50000 | + | 110000 | ÷ | ( | x | + | 60 | ) | × | x | = | 850 | x |
| Multiply both sides of the equation by: | ( | x | + | 60 | ) |
| 50000 | ( | x | + | 60 | ) | + | 110000 | x | = | 850 | x | ( | x | + | 60 | ) |
| 50000 | x | + | 50000 | × | 60 | + | 110000 | x | = | 850 | x | ( | x | + | 60 | ) |
| 50000 | x | + | 50000 | × | 60 | + | 110000 | x | = | 850 | x | x | + | 850 | x | × | 60 |
| 50000 | x | + | 3000000 | + | 110000 | x | = | 850 | x | x | + | 51000 | x |
| 160000 | x | + | 3000000 | = | 850 | x | x | + | 51000 | x |
