| y | ( | 1 50 | + | y | ) | ÷ | ( | 1 20 | − | y | ) | = | 9 500000 |
| Multiply both sides of the equation by: | ( | 1 20 | − | y | ) |
| y | ( | 1 50 | + | y | ) | = | 9 500000 | ( | 1 20 | − | y | ) |
| y | × | 1 50 | + | y | y | = | 9 500000 | ( | 1 20 | − | y | ) |
| y | × | 1 50 | + | y | y | = | 9 500000 | × | 1 20 | − | 9 500000 | y |
| y | × | 1 50 | + | y | y | = | 9 10000000 | − | 9 500000 | y |
