| 20000 | ÷ | x | + | 40000 | ÷ | ( | x | + | 60 | ) | = | 250 |
| Multiply both sides of the equation by: | x |
| 20000 | + | 40000 | ÷ | ( | x | + | 60 | ) | × | x | = | 250 | x |
| Multiply both sides of the equation by: | ( | x | + | 60 | ) |
| 20000 | ( | x | + | 60 | ) | + | 40000 | x | = | 250 | x | ( | x | + | 60 | ) |
| 20000 | x | + | 20000 | × | 60 | + | 40000 | x | = | 250 | x | ( | x | + | 60 | ) |
| 20000 | x | + | 20000 | × | 60 | + | 40000 | x | = | 250 | x | x | + | 250 | x | × | 60 |
| 20000 | x | + | 1200000 | + | 40000 | x | = | 250 | x | x | + | 15000 | x |
| 60000 | x | + | 1200000 | = | 250 | x | x | + | 15000 | x |
