15 | ÷ | ( | 10000 | + | y | ) | = | 6 | ÷ | y |
Multiply both sides of the equation by: | ( | 10000 | + | y | ) | , | y |
15 | y | = | 6 | ( | 10000 | + | y | ) |
15 | y | = | 6 | × | 10000 | + | 6 | y |
15 | y | = | 60000 | + | 6 | y |
15 | y | − | 6 | y | = | 60000 |
9 | y | = | 60000 |
y | = | 60000 | ÷ | 9 |
= | 60000 | × | 1 9 |
= | 20000 | × | 1 3 |
y | = | 20000 3 |
y | = | 6666.666667 |
